The reported problem is not reproducible in OpenSSL.  Any memory
corruption issue is highly likely to be some logic error in the
application.

It also seems rather likely that reading malformed (e.g., as in this
case,truncated) PEM objects is not that uncommon, and any issues in the
error path would have surfaced multiple times before.  Occam's razor, in
this case, strongly favours the calling code rather than OpenSSL.
