I am not sure but i would say no, since all those errors have main and run_test
on the stack

I tried to run valgrind on my minimized testcase, but it did not report any
errors regarding crypt32
I need to research more why this error is not reported.
I would guess the memory is allocated again and thus also valid again.
I will try to create a patch which does not free memory, only make it
unaccessible for VG, so it is raises a error when the program is accessing it.

Looks like it has not been applied yet, if this is the right way to also solve
the crypt32 problem i can create/send a patch for it
