Oh, there *is* a reson (or a few).

The very first question you should ask is where exactly is it
crashing? Use debugger to find out.

We think this could probably be due to sufficient memory not available
to the 64-bit application.

You have not presented any reason why you'd think that.

Hi Paul,

I ran a truss on the application to have a trace. It resulted into
this ...

lwp_sema_post(0xFFFFFFFF7D003D60) = 0
lwp_mutex_lock(0xFFFFFFFF7E72B068) = 0
read(39, " 3 e c 0 a 8 f 1 c 7 d 0".., 512) = 512
lwp_mutex_wakeup(0xFFFFFFFF7E72B068) = 0
time() = 1205757131
lwp_mutex_lock(0xFFFFFFFF7E72B068) = 0
Incurred fault #6, FLTBOUNDS %pc = 0xFFFFFFFF7E449BBC
siginfo: SIGSEGV SEGV_MAPERR addr=0x0FAE0350
Received signal #11, SIGSEGV [default]
siginfo: SIGSEGV SEGV_MAPERR addr=0x0FAE0350
*** process killed ***


Seems there is some memory access violation. But the thing is, this
same application compiled in 32-bit mode, run on the same environment
(same machine) fares well. So if it were something to do within the
code, in way of accessing memory wrongly, it should have surfaced in
the 32-bit version as well.
