If you don't have qemu sources than I really don't care. By definition you're 
not going to be able to do anything useful even if you do figure out what the 
problem is.  Note that there's no requirement that you run gdb on the target 
itself. Remote debug (e.g. via gdbserver on linux) is a well established 

Likewise for debugging stripped production binaries, my answer is "don't do 
that". There are very rare cases where a bug goes away on a debug build, but 
in those cases any instrumentation you add is also liable to make the bug go
