openssl-1.0.1/crypto/asn1/a_bitstr.c

Unassigning myself, this isn't a curl problem.

You should report this upstream if you can provide a reproducible example. Also: Check if this is still broken in openssl 1.0.1a.

I'll try to get a test cert from the company that issues them, cause I think it might be some peculiar field value that gets "wrongly" parsed to ASN1 structure.

p.s. I worked fine prior to update to openssl-1.0.0 version.

Status?

The problem has resolved. (I guess with updates)
(same cert, same script, curl-openssl works)
