HP-UX 11 64bit, compiled with HP ansi c compiler. Python version 2.2.1rc2 >>> f=open(some_big_file) >>> f.readlines() Pid 23292 received a SIGSEGV for stack growth failure. Possible causes: insufficient memory or swap space, or stack size exceeded maxssiz. Memory fault(coredump) Happens when last line of file lacks a terminating \n, also the file has to be big enough (my example is about 2K in size) Oddly, xreadlines() can be created, but attempting to iterate over it crashes before the first line is returned: >>> f=open(some_big_file) >>> lines=f.xreadlines() # OK so far >>> for line in lines: ... print line # never gets here ... Pid 23257 received a SIGSEGV for stack growth failure. Possible causes: insufficient memory or swap space, or stack size exceeded maxssiz. Memory fault(coredump) I'll try 2.2.1 final.
Logged In: YES user_id=6380 I can't reproduce this on Linux. Can you upload the data file or (preferably, if you have access) on a Linux system, with Python 2.2.1? I'd like to see if this is data dependent or platform specific before we go any further with this.
Logged In: YES user_id=8911 I think it's compiler/architecture dependent. It works fine on Linux. Re-compiling Objects/fileobject.c without optimisation cures the problem. I think HP's compiler is a bit dodgy, because the last version of Python was dumping core until I recompiled longobject.c. I would try compiling with gcc but I don't have it on our HP machine. I think the README should maybe warn HP PA-RISC 2.0 users that the C compiler will occasionally break things. Thanks for your time.
