Re: Is this the right list...
Excellent! Thanks. Next time, I'll do that.
Now, I know this isn't the right list, but does anyone out there know of a
forum or list for Electric Fence? Or a better or more suitable product for
finding memory problems? I'm using gdb and Electric Fence and have a
particularly pernicious memory bug that bombs out in the middle of strcmp in
the bowels of the ODBC library.
