Description:
------------
In gnupg_verify() gets called:
char * gpgme_data_release_and_get_mem (gpgme_data_t dh, size_t *length), where second argument should be pointer to size_t type variable. However, gpg_plain_len variable is defined as int which on 64bit OS is 4 bytes, but size_t on 64bit OS is 8 bytes. Memory gets corrupted.
Here is the patch that fixes it:
