Sure -- but that's not the problem (and it won't be the problem).
Of all the faith-based initiatives Bush funded, faith-based software maintenance has to be the worst. Smilie Bottom line is, you don't know why it crashed, don't know why it stopped crashing, and don't know if the problem is truly solved yet or not. All we know is that something trashed some memory somewhere somehow. Time for a memory debugger.

All this odd stack rearranging makes me more and more suspicious of memory trashing, not less! When it works perfectly it works perfectly, but one mistake and you're mangling your own stack frame. It could also be a disguised array-bounds problem, these macros are using hidden stack variables and writing beyond them could smash your stack too.

maxrsessiz

maxrsessiz(5)							File Formats Manual						     maxrsessiz(5)

NAME

       maxrsessiz, maxrsessiz_64bit - maximum size (in bytes) of the RSE stack for any user process on the Itanium-based platform

VALUES

   Default
   Allowed values
DESCRIPTION

       Itanium-based  systems  utilize a per-process register stack in main memory (for more information see the Intel IA-64 Architecture Software
       Developer's Manual, Volume 2, Chapter 6). This stack moves registers between the physical registers and main memory and	is  maintained	by
       the Register Stack Engine (RSE).  determines the size of this stack.

   Who is Expected to Change This Tunable?
       Anyone.

   Restrictions on Changing
       Changes to this tunable only take effect after a reboot of the system.

   When Should the Value of This Tunable Be Raised?
       should be raised if user processes are being terminated with the error due to overflow of the RSE stack.

   What Are the Side Effects of Raising the Value?
       User processes will dedicate more virtual memory to the RSE stack. This will result in less virtual memory being available for data alloca-
       tion.

   When Should the Value of This Tunable Be Lowered?
       This tunable should be lowered only if swap space is at a premium on the system, since virtual memory for  the  RSE  stack  still  requires
       matching  swap  reservation  or	allocation.  Serious consideration should be given if is being lowered below the default as this may cause
       unexpected failures of user applications on RSE stack overflow.

       This tunable is best left unchanged without complete and detailed knowledge of the RSE stack usage of the machine workload.

   What Are the Side Effects of Lowering the Value?
       Lowering this tunable will limit the amount of memory available for RSE stack usage per process.  This could cause processes with large RSE
       stack requirements to terminate with a error.

   What Other Tunable Values Should Be Changed at the Same Time?
       None.

WARNINGS

       All  HP-UX kernel tunable parameters are release specific.  This parameter may be removed or have its meaning changed in future releases of
       HP-UX.

       Installation of optional kernel software, from HP or other vendors, may cause changes to tunable  parameter  values.   After  installation,
       some  tunable  parameters may no longer be at the default or recommended values.  For information about the effects of installation on tun-
       able values, consult the documentation for the kernel software being installed.	For information about optional kernel  software  that  was
       factory installed on your system, see at
