I think I need a better test case.

No matter what DLL I use, if I put the above in a shell script (adding a
'\' to the end of each line) and execute it, I get the below output and
my process table fills up /usr/bin/sh processes.

If I reduce my PATH to just /usr/bin, the xprobe_comp sits there and I
get lots and lots of /usr/bin/sh processes showing up in ps output and
eventually I have to power-cycle my system to recover.

The script:

#!/bin/sh
./xprobe_comp -v 2 -o atlconf.txt -O 9 -A 25 -Si nof77 0 -V 448  -Fa \
ic '-fno-common' -Fa sm '-fno-common' -Fa dm '-fno-common' -Fa sk \
'-fno-common' -Fa dk '-fno-common' -Fa xc '-fno-common' -Fa gc \
'-fno-common' -Fa if '-fno-common' -b 32 -d b .

The output:

   'none' : 'none' '-fno-common'
   'none' : 'none' '-fno-common'
   'none' : 'none' '-fno-common'
