Anyway there's something weird going on there. It shouldn't crash on
that line. So either gcc optimizations confused gdb and it's actually
crashing elsewhere (recompiling+reinstalling the plugin without -O2
parameter would help with this),

or there is some memory corruption
which is probably going to be tricky to find without valgrind.
That's a virtual machine inside Xen, may be a problem?
