I've come to a standstill with v 5 on OS X (10.2.6).  After months of
back-and-forth with Wolfram support, they have declared it a personal
problem.  (Can't duplicate but won't tell me what machines they tested
it on.)

Apparently the problem is machine dependent-- it happens with 100%
reliability on our fast dual processor machines, but not on our
laptops. To see the problem (or not), put a series of expressions of
the form (multiple expressions accelerates the crash) into a cell and

. . . .

Also crashes Mathematica with other image formats.  I would appreciate
hearing how others fare with this (esp. w.r.t. machine).  Wolfram support
accuses me (literally!!) of having an impure system.  Impure thoughts
maybe, but I replicated this on a machine right out of its carton, with
-only- Mathematica installed.  (Hmm, maybe they meant Mathematica....)

I'm sorry for sending what amounts to a bug report to the list, but
I went through channels with no joy.  Unfortunately, this feature is
important to a series of my applications, hence my frustration.

A few other notes: -  Even if this fails to crash Mathematica (on a PB
for example), it's an order of magnitude (!!) slower than 4.2

- Under Panther, any export call of this type is DOA (dead stall), whatever the machine.

- Nothing like this happens under v 4.2 (even under Panther), but
it is apparent from my observations that Mathematica's converter,
gif.exe/pnm.exe, has a memory leak.  The converters (4.2) are unusably
slow under Panther.
