Buffer overflow error

I'm experiencing a buffer overflow error when executing the following
surface command:

surface $inputFile -G$outputFile -I100k -R0/360/-90/-60 -T0.25 -Lld -Lud

What's odd is that I see the error when I run this command in my shell
script. If I run it manually from the command line, everything works.

Here's some system info. Let me know if there's any other information
needed:

Linux version 2.6.32-131.4.1.el6.x86_64 (
[email protected]) (gcc version 4.4.5 20110214 (Red
Hat 4.4.5-6) (GCC) ) #1 SMP Fri Jun 10 10:54:26 EDT 2011

And here's the error itself:
