Do you use dlopened modules?  If yes, try adding -export-dynamic to the
link flags of the program, and try enabling global symbol resolution for
opened modules.

I'll post a testsuite addition on libtool-patches to try out.

Do you mix C++ code with other code, e.g., code compiled with the C
compiler?  Some non-GCC compilers may need other switches for exception
handling to work right, e.g., +eh for the HP-UX compiler.
