Hmm, I don't know. I know the DWARF information is there, but I'm not sure why GDB isn't picking it up. I'll add it to my list of things to check, but for now I don't know what the issue is. There's some logging in gdb (I don't quite remember the option, but apropos jit will probably tell you) that might tell you whether it detects the jit code and just doesn't use it for some reason or whether it doesn't pick up on the breakpoint. On the julia side, the registration with GDB should happen here ( https://github.com/JuliaLang/julia/blob/ce1e856975af4dc8fc12dac8f5526c92feda60cb/src/jitlayers.cpp#L178), in latest master at least.
