This is most definatelly the Amd64 specific bug. You see, the pointer
is 0x00b37a95 while it should be more like, 0x00b37a95,
where X is some hex number.

What happens is probably,

void *p1; // - original pointer
void *p2 = (void*)(int)p1;

ie. they cast it to int and then back to a pointer. Works on all 32-bit
platforms :) Fails on all 64-bit ones.

PS. Forwarded upstream to the same bug.
