Bus Error - Determining Script Name in GDB

Hi

I am using PHP 5.2.3. In the Apache error log file I see:

[Mon Jul 13 16:15:32 2009] [notice] child pid 21521 exit signal Bus error (7)

After many attempts, I have caught the following backtrace:

The problem appears to be in file_get_contents. Is there any way I can determine which script was being run at the time?

Thanks in advance,
