I was talking about the kernel, not the program. The bug is in the kernel if the program runs on Linux but not FreeBSD. He needs to find out which Linux system call is blowing chunks, then he needs to find which line in that call is blowing chunks, then he needs to breakpoint there with the kernel debugger and find out how many repetitions are necessary before it blows chunks, then he needs to set the breakpoint again and step through that many times minus one, and then he needs to watch it so he can see what's actually blowing chunks. And if you think that was a run-on sentence, it's because tracking a kernel bug without a dump is a run-on procedure. Further, since most of us don't have Mathematica to test with, it's probably him or no one. And running kdb is a question that's better answered by Bruce or someone else who uses the thing on a regular basis.
