So the problem is not GDB, but the debug build of Emacs? If so, you can run the optimized build under GDB as well, just be sure to use the "-g3" switch to GCC when you build, and don't strip the binary (i.e., if you install the build, do NOT use "make install-strip"). The backtrace will be somewhat less informative, but it is usually still useful. However, please remember to invoke Emacs in X-synchronous mode by using '-xrm "emacs.synchronous: true"' on the command line, when the issue is related to X protocol errors, because otherwise X errors are reported asynchronously, and it is impossible to know which code caused an X error.
