I did a similar thing and ran several programs (midori, gnome-about, vlc)
using LD_PRELOAD, simple test programs linked using -lprofiler, and the
complete test suite and could not produce any crash (all on amd64).
I think this bug could be downgraded to 'important', as it works for
others, and could just be an application issue and not a perftools
bug at all (e.g. access via an uninitialized pointer, given that this
points to 0xb5=231 which is very small and not correctly aligned for
an object of that type).
