[LLVMdev] Missing symbols in pass stack trace

I'm working on a pass (both LLVM and the pass have been compiled in 
debug+asserts mode) but when the pass crashes in the stack trace printed 
by opt the names of the functions inside my pass don't appear (see 
frames 14-16). How can I have them displayed?> cafxx at ubuntu:~/Projects/llvm2/Debug+Asserts/bin$ clear && ./opt

Looks like your shared library is not being compiled with symbols.  Did you
verify that your sources are compiled with -g?
