The crashes I've seen are because objects were accessed after beeing
freed i.e. they were not marked during. The root cause of the problem
is that sometimes the values returned from allocation rutines (and
therefore put on the stack) are not the address of the cell, but the
address of the cell+4. I assume this is due to how compiler (Visual
Studio 2003 in my case) implements object layout in face of
inheritance.
I assume those crashes happen on win and not on mac (otherwise I would
expect similar crashes happen on mac) because of differences between
Visual C 2003 and gcc.
In every version of VC++ that I know of there is an option on
alignment, I "think" that it defaults
to 8 byte boundaries.
It is not uncommon to have to change this when doing certain things.
I would think that if that was the problem
you would want to change your compiler settings before changing code.
