Hi all,
there is a bug in libopensc/asn1.c in line 1004, which triggers a
segmentation fault. In short, the last parameter to sc_debug may (and in
my case will) dereference NULL.
This bug was introduced with changeset 4118. Befor revision 4118 this
behavior only occured with debug level >= 6.
Best regards,
Andre Zepezauer
