[openssl.org #1680] Possible Bug: x509_name_ex_d2i segmentation fault under IA-64

[Brian Smith via RT]

Detail:
When writing a function to generate a CSR via OpenSSL on IA-64, the
X509_REQ_set_subject_name function eventually calls x509_name_ex_d2i which
causes a segmentation fault under IA-64. This code works properly on
Solaris, IRIX, win32 (cygwin), and x86_64

Additional Details:
OpenSSL compiled debug allows the function to operate properly without
crashing
Inserting printf("here") statements between lines of x509_name_ex_d2i also
allows the function to operate without seg fault when built normally

Possibly Known Related Cases:

Test Setup:

Linux 2.6.5-7.252.PTF-sn1 SMP
Openssl 0.9.7m Configured linux-ia64 -fPIC
gcc version 3.3.3 (SuSE Linux)

GDB Dump:

Program received signal SIGSEGV, Segmentation fault.

0x40000000000a58c0 in x509_name_ex_d2i ()

(gdb) where

#0  0x40000000000a58c0 in x509_name_ex_d2i ()
