8914.0. "Some sia functions coredumping DU V4.0b" by NETRIX::"[email protected]" () Thu Feb 20 1997 22:37

DU V4.0b C2 security.

Hello all,

I have a customer who since upgrading from V3.2d1 to V4.0b is having
problems with the sia functions. Her application now coredumps. The
source code is below. (sia_ses_init)

When I tested the code it seemed to work when I was using csh but 
not when I used ksh or sh and when I tuned optimization off the compile it 
worked for ksh. (standard C compiler)

Any help on the would be greatly appreciated.

Thank in advance

Lance.

    char *argv[2] = { "check", NULL };

    retval = sia_ses_init(&entity, 1, argv, NULL, user, NULL, 0, NULL);

WAG:  does it work better if you compile it with -D_REENTRANT (or -threads)?

Thanks -threads worked around the problem.

There should be a bit of the documentation, or a STARS article, or SOMETHING
which points out that SIA when configured to use DCE causes the application
to become multithreaded (like it or not!), and this demands that the calling
application be properly built...
