This sounds like an OS problem that should be tracked down!

Is malloc returning NULL by any chance?

Even better, can you run your program with par:
par -s -i -SS prog options

and see if you get any messages about brk failing?

I couldn't find any known problems with this patch. It is a recommended patch
for your machine/OS. You ought to have a performer patch installed whatever
though. You'd need 1392 and 1347. I'll paste Sharon Clay's release announcement
at the end of this. You could try the Pf patches with 1566 but it maybe worth
getting a support call logged with your local office and getting all the
recommended patches for your situation installed rather than cherry picking one
or two off the recommended list.

************* Announcing IRIS Performer 2.0 Patches ***************

Bug fix patches for Performer 2.0 have been released!
These patches are binary compatible with and
update all of Performer2.0[.X], including the 2.0.1 compatibility DSOs
shipped with IRIX6.2 and Performer 2.1.

There are three patches:
        patch 1414 for IRIX 5.3-6.1 (requires that you have Performer2.0).
        patch 1392 - dev for IRIX 6.2 (requires that you have Performer2.0).
        patch 1347 - eoe for IRIX 6.2

These patches fix the bugs listed in the 2.0 bug list in the web page
        http://www.sgi.com/Technology/Performer/bugs2.0.html
The patch release notes will be available from the Performer web page ASAP.

Patches 1347, 1392, and 1414 are being distributed by the following
methods:

  - Request your SGI support provider to provide them on tape.  In
    North America, call 1-800-800-4744.  Outside of North America
    contact your local service provider.

  - Patches 1347, 1392, and 1414 will be included on the next
    IRIX Patches CD, shipped quarterly with Supportfolio.

  - The three patches will be included in the next update of
    SupportFolio Online, typically updated every two weeks:

      http://www.sgi.com/Support/patch_intro.html

  - For those with an immediate urgent need, they are temporarily
    available via anonymous FTP at this location:

    ftp://sgigate.sgi.com/pub/Performer/src/pf2.0/patch1347/
    ftp://sgigate.sgi.com/pub/Performer/src/pf2.0/patch1392/
    ftp://sgigate.sgi.com/pub/Performer/src/pf2.0/patch1414/

    Please note that the total size of these patches is more than
    300MB.  To aid in downloading only the parts needed, each of
    the above directories contains the component files of the
    patch, e.g.:

    README.patch.1392                 38 Kb    Wed Jul 24 14:34:00 1996
    patchSG0001392                     9 Kb    Tue Jul 23 16:42:00 1996
    patchSG0001392.dev_sw          48671 Kb    Tue Jul 23 16:44:00 1996
    patchSG0001392.dev_sw32        56218 Kb    Tue Jul 23 16:46:00 1996
    patchSG0001392.dev_sw64        31067 Kb    Tue Jul 23 16:47:00 1996
    patchSG0001392.idb               537 Kb    Tue Jul 23 16:47:00 1996
    patchSG0001392.man              2619 Kb    Tue Jul 23 16:47:00 1996
    patchSG0001392.src              2979 Kb    Tue Jul 23 16:47:00 1996

    If you do not use the sw32- or sw64-based subsystems you need not
    bother downloading those files.  The 'no extension' and '.idb'
    files are required in order to install the patch.

    Also note that Performer 2.0[.1] must be installed prior to
    loading the patches.
