Segfault toward end of hotspot-comp build (original) (raw)

Hi Charles,

It's not a segfault, but rather hitting an assertion when initializing the VM in the test gamma run, during the last part of the build process. The VM is already fully built and linked by then, so it looks like the VM compiled cleanly.

A wild guess of what caused this problem would be: something's not right in your HotSpot code, specifically, src/share/vm/runtime/arguments.cpp, in Arguments::set_heap_size(), or in src/share/vm/runtime/globals.hpp.

The assertion is indicating that someone is trying to set a flag with the type uintx (in Arguments::set_heap_size(), with either of the two macros, FLAG_SET_CMDLINE or FLAG_SET_ERGO), but the flag was declared to be of another type (in globals.hpp).

I'd suggest cleaning the source directory (at least arguments.cpp and globals.hpp) and try building it again. I've just done building the current tip of hotspot-comp (with no other patches applied), and nothing weird happened:

cd linux_amd64_compiler2/product && ./test_gamma java full version "1.6.0_25-b06" Using java runtime at: /home/rednaxelafx/sdk/jdk1.6.0_25/jre java version "1.6.0_25" Java(TM) SE Runtime Environment (build 1.6.0_25-b06) OpenJDK 64-Bit Server VM (build 22.0-b02-internal, mixed mode)

  1. A1 B5 C8 D6 E3 F7 G2 H4 ...
  2. A8 B4 C1 D3 E6 F2 G7 H5

Regards, Kris Mok

Perhaps I've got an environmental issue here, but I'd like to be sure I'm building hotspot-comp properly. What's causing this?
