[Switching to Thread 1 (LWP 1)] 0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1 (gdb) where #0 0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1 #1 0xfeb9028c in raise () from /lib/libc.so.1 #2 0xfeb60578 in abort () from /lib/libc.so.1 #3 0x00010e1c in main () at /vol/gcc/src/hg/master/local/gcc/testsuite/g++.dg/tree-ssa/pta-delete-1.C:23 yet gdb shows that y = 2 at this point. * pr45967.c: Thread 2 received signal SIGABRT, Aborted. [Switching to Thread 1 (LWP 1)] 0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1 (gdb) where #0 0xfec5344c in __lwp_sigqueue () from /lib/libc.so.1 #1 0xfeb9028c in raise () from /lib/libc.so.1 #2 0xfeb60578 in abort () from /lib/libc.so.1 #3 0x00010c94 in main () at /vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/torture/pr45967.c:19 Again, the test aborts although gdb shows i = 1. Unless someone has an idea what might have caused this, I'll have to run a reghunt.
