Hello all !
I recently stumbled upon a strange result while using gpgme_data_seek(data, off,
So, I read the source code for this function (and had a quite hard time crawling
to finally find mem_seek).
It looks like there is an error in the function : the offset is negative but is
then substracted from the position, which results in an out-of-bounds pointer
and then in a crash.
Proposed "patch" : file "src/data-mem.c", line 140, turn the "minus" into a "plus".
Hope that helps,
