Thank you very much for the hint. Indeed I have not --enable-threads.
Rebuild egcs with the flag and the problem goes away.
I'm now able to build and run omniORB2 (a multithread C++ ORB) and its
testsuite without optimization.
However, when I specify -O2, there are loads of warnings about variables
might be used uninitialized. These warnings do not appear with -O2 on x86
linux. The warnings include 'struct cp_eh_info * __exception_info' which
looks like it is EH related.
All the resulting binaries core dump in a global constructor. I'll look
into what is wrong in the global constructor some time. Does this ring a
Any suggestion as to what to look into is much appreciated.
This problem occurs both with --enable-haifa and --disable-haifa.
The test was done with egcs_980802.
