I'd definitely immediately add a "me too". Our compiler also generates  
dispatch stubs without debug info in a number of cases, and adding  
code to gdb to recognize all possible variations on all architectures  
we support (about 8 by now, I think) is not something anyone has felt  
up to figuring out yet. In the long term, it also does not seem  
tenable to add pattern recognition to gdb for stubs generated by all  
possible compilers (and possibly different versions of those compilers).
