It looks like GLib profiler is reading before each allocation (assuming 
it's own padded allocator was used), but some allocation seems to be 
from calloc instead of the profile alloc. Valgrind bad read are all 
targetting stuff within _dl_init (dl-init.c:34), so basically, stuff 
that runs before your main. A talk with the authors on how dynamic 
library with init function are supposed to work would be nice.
