The macros DECLARE_PEM_rw and IMPLEMENT_PEM_rw, which are defined in crypto/pem/pem.h, produce a bunch of functions for reading and writing structures in various ways (with a BIO, from a FILE *, from a string buffer, etc). In this case, I think the function you're looking at is produced by the macro invocation "IMPLEMENT_PEM_rw(X509_AUX, X509, PEM_STRING_X509_TRUSTED, X509_AUX)" in crypto/pem/pem_xaux.c.

Possibly it's hanging waiting to read something from stdin.
