Hello.
I have a strange core dump during cppunit test suite run.
Does someone else see it?
I've checked that my compiler can catch exceptions in 64-bit programs (I
mean it is not affected by
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59788 )
Any other ideas?
btw, did you patch libtool as needed to avoid "optimisation"?
Hi.
What patch do you speak about?

commit 525cddd2bcea4c565d6dd1d2d55dd1de1a476b67

libtool: opt_duplicate_compiler_generated_deps is harmful on Solaris
Fix for http://debbugs.gnu.org/cgi/bugreport.cgi?bug=16452.
* build-aux/ltmain.in (libtool_validate_options): disable the
opt_duplicate_compiler_generated_deps optimization for Solaris2 so
that gcc-4.9+ compiled C++ code with -Wl,-Bdirect on 64-bit Solaris
x86 can avoid unwinding failures caused by accidental mixing of the
libc and libgcc_s unwinders in a single executable.

many packages include a version of ltmain.sh, I think cppunit is one, so
if you don't replace it then you may need to patch it as well.
for good measure as well, prior to gcc49, there was a bugfix to ro@'s
patch that should theoretically be applied in the gcc tree (that is, if
you backported):
