Thanks for the test case! This results in the following bt: #0 0xf7f38168 in _dl_fixup () from /lib/ld-linux.so.2 #1 0xf7f3ea34 in _dl_runtime_resolve () from /lib/ld-linux.so.2 #2 0x00010ba8 in main (argc=0x1, argv=0xffb036e4) at a.c:7 The bt looks similar for SIGBUG and SIGSEGV. > If I recompile Qt3 in debug mode (with -O0), it works fine. > > Somehow I feel like blaming the toolchain or gcc.

Glibc is the same. Could it be possible that qt3 overwrites memory somewhere? Wrong results for t.hour() would also speak for that.
