--- Comment #34 from Gustavo <bugzilla at addax.cr> ---
Hi,

I just tried the latest patch version against the trunk and it compiles fine. 
I tried pdfsig with different PDF files on my end and it works as expected
EXCEPT on one signed file and it crashes (coredump).

Maybe Hans-Ulrich could take a look at it using my file:

http://bit.ly/2u9AjQI

pdfsig does not crash without the patch, it just says 

"Unimplemented Feature (0): Unable to validate this type of signature".

Patched pdfsig says:

"Signature #1:
  - Signer Certificate Common Name: XXXXXXXXXXXXXX
Segmentation fault (core dumped)"

It does get the Common Name correctly.

Cheers
