path length of executable causes a hang

Hi

We are running into the following behavior:

An executable, say, "om" is built into a directory.

I copy this executable into a directory with absolute path such as: /home/eng/abhi/test/bin

Then from a working directory I do: /home/eng/abhi/test/bin/om

The program executes fine.

Next, I copy the same binary executable into a directory with a much longer path such as: /home/eng/abhi/ABCD1234ABCD1234/AnotherTest/bin

Then from the same working directory as previously, I try to run: /home/eng/abhi/ABCD1234ABCD1234/AnotherTest/bin/om

Doing so creates a hang.

Any hints?
