I assume you got this backtrace with a liboil compiled with -O0. If that's the case, this is _not_ the place where it crashes with -O2. I wasted several hours at this point myself, sadly :-/ If you care you can try it with an unmodified liboil, at the crash `bt` won't really work, but you can do `x/20i $pc`, that'll show the code I posted in my report (starting at the <=== SEGV marker). You should be able to get the same trace as I via `x/20i ($pc-0x2b)`. Cheers, Christian Aichinger
