The code in question is attached. I have the following information: $ g++-3.3 -v Reading specs from /usr/local/gcc-3.3/lib/gcc-lib/i686-pc-linux-gnu/3.3/specs Configured with: ../gcc-3.3/configure --prefix=/usr/local/gcc-3.3 --enable-threads Thread model: posix gcc version 3.3 The code is accepted by GCC 2.95.3, 3.0.4, 3.1, and 3.2. With all of these versions, the code works correctly with -O3 -fPIC (and various other combinations of -O and -fPIC). The code works with 3.3 if -O2 or lower is specified, or if -O3 without -fPIC/-fpic is used. One interesting thing is that if the variable local_foo is declared as: static foo* local_foo; then it works. It also doesn't work if local_foo is declared as a non-static global (rather than in an anonymous namespace), presumably because anonymous namespace members aren't (IIRC) linked as static in GCC. I only have 3.2, so it's possible this was introduced in later 3.2 versions rather than the 3.3 branch. BTW, I've checked, and the resulting binary does use the gcc 3.3 versions of libgcc and libstdc++, so it's not that. Release: 3.3 Environment: RedHat 7.3, AMD Athlon, glibc 2.2.5, kernel 2.4.19, binutils 2.11.93.0.2 How-To-Repeat: Here is exactly what I'm seeing. This is with a printf that runs right before we exit from main; the version attached has the include of <stdio.h> and the printf call commented out. $ g++-3.3 -O3 -fPIC gccbug.cpp $ ./a.out Segmentation fault $ g++-3.3 -O2 -fPIC gccbug.cpp $ ./a.out I guess we didn't crash $ g++-3.3 -O3 gccbug.cpp $ ./a.out I guess we didn't crash $ g++-2.95.3 -O3 -fPIC gccbug.cpp $ ./a.out I guess we didn't crash $ g++-3.0.4 -O3 -fPIC gccbug.cpp $ ./a.out I guess we didn't crash $ g++-3.1 -O3 -fPIC gccbug.cpp $ ./a.out I guess we didn't crash $ g++-3.2 -O3 -fPIC gccbug.cpp $ ./a.out I guess we didn't crash Comment 2 Wolfgang Bangerth 2003-05-20 01:16:37 UTC State-Changed-From-To: open->analyzed State-Changed-Why: Confirmed. This is a smaller snippet (it has nothing to do with namespaces): ---------------------------- int* i; int& get_x() { return *i; } int main() { int j; i = &j; get_x(); } -------------------------- It crashed in get_x: g/x> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -O3 -fPIC x.cc g/x> ./a.out Segmentation fault Note that we really need both -fPIC and -O3. This crashes with both 3.3 and present mainline. It doesn't with 2.95 and 3.2.3, so it's definitely a regression worth fixing! W.

That's pretty weird. I can reproduce this with most a 3.4 snapshot from 2003-05-15 as well as a 3.3 snapshot from 2003-05-16. I compared the assembler output, and instructionwise they are equal, but there are some additional linkonce things in your output. I don't know enough about this stuff to tell whether that's relevant. I'll update now to present HEAD and check+report again once the bootstrap is done.

The problem is the following instruction: addl GLOBALOFFSETTABLE_,_GLOBAL_OFFSET_TABLE_, %eax This tells the assembler that we want the difference between the adress of this addl instruction and the start of the global offset table to be added to %eax. When translating this request into relocation records an R_386_GOTPC relocation is used. However, this relocation calculates the difference between the place where the relocation takes place and the start of the global offset table. Hence the assembler must add an addend to fix up the difference between the address of the addl instruction and the address of its immediate operand (the latter is the place of the relocation). Now in the %eax case gas emmits the 0x05 opcode for addl imm32,%eax with a length of 1 byte. If the register isn't %eax the assembler has to use the longer 0x81 0xc3 opcode. Both opcodes are followed by the immediate 32bit Operand. I.e. if %eax is used the addend for the R_386_GOTPC relocation must be 1 but for all other registers it must be 2 due to the different length of the opcode. This is what some gas versions seem to get wrong. So what should we do with this report? Do we want to work around this bug in gcc or should we close it and tell people to upgrade binutils. The bug is fixed at least since 2.12.90.0.15 20020717 (SuSE). regards Christian -- THAT'S ALL FOLKS! Comment 17 Drea Pinski 2003-05-25 02:31:36 UTC Should we have a workaround for the gas bug or should we change the requirements for gas to higher? Comment 18 Eric Botcazou 2003-05-25 06:09:02 UTC I don't see how we could devise a robust workaround: it is my understanding that the register allocator is free to assign any GP register to the pc_thunk. But you might want to ask the maintainer of the x86 port.

There's no reason I shouldnt' believe this. But we then need to document the requirement on newer binutils, possibly pointing to this particular PR. Would you mind, or...?
