pldebugger's readme said that I should file bugs here. If I'm in the wrong place, just let me know where to direct this report.

Here's our gcc version:

gcc --version

My C is rusty, so I am afraid I don't have a great suggestion other than reverting the change :)  Please let me know if I can do anything to help.
