I'm looking at that. -Doug 31 Oct 2007 14:52:04 -0000, rguenth at gcc dot gnu dot org <[EMAIL PROTECTED]>: > Starting with r129030 tramp3d-v4 segfaults on startup if compiled statically > with -fopenmp. This can be reproduced with the preprocessed testcase from > http://www.suse.de/~rguenther/tramp3d/tramp3d-v4.ii.gz (x86_64) and compiling > with -fopenmp -static (optimization does not change the effect). > > Author: jason > Date: Fri Oct 5 05:35:46 2007 > New Revision: 129030 > > URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=129030 > Log: > 2007-09-13 Doug Kwan <[EMAIL PROTECTED]> > > * gcc/gthr-posix.h (__gthread_cond_broadcast, __gthread_cond_wait, > __gthread_cond_wait_recursive): Add to extend interface for POSIX > conditional variables.
