Status: Feedback
Bug Type: Reproducible crash
Operating System: Solaris 10 SPARC u6
PHP Version: 5.2.9
New Comment:
I no longer think this is a PHP bug. I believe the problem is actually
with the build of gcc.
Configuring php without --enable-debug but setting CFLAGS to -g doesn't
segfault (indicating the problem is with gcc). So I tried again after
setting CFLAGS to -O1 and make test runs fine.
As such I think the bug is probably in the gcc optimisation process.
I'll investigate this further, but if this is the case then it's not
relevant to PHP.
If the original poster wants to try 'export CFLAGS=-O1' to see if he
encounters the same behaviour then this bug can probably be closed.
Cheers.

I am experiencing the exact same issue as the original submitter on a
Sparc 64-bit sun4u system.
I recompiled with --enable-debug to obtain a backtrace to submit but
having done so make test no longer seg faults. This is reproducible:
without debug it seg faults at the start of make test, with debug
enabled and all other options identical it doesn't. Given that I can't
get a backtrace what alternative information can I provide?
