Hi Lou, About two weeks ago, I posted a valgrind error log on the list, which you can find here: http://durktalsma.xs4all.nl/valgrind.log This is a result from a regular AMD Athlon XP single CPU machine (1 Gig RAM). I'm under the impression that some reports are spurious, at least some of the "Conditional jump or move depends on uninitialised value(s) " or "Use of uninitialised value of size 8" messages. I checked one or two occurrences of these, and the code in question looks okay. FWIW, I'm currently trying to trace down a pretty bad memory leak (presumably related to AI) in my development copy, but I'd be surprise that that is something causing problems on your system. Cheers, Durk P.S., have you tried using gdb? Valgrind is a pretty heavy tool, and when it comes to tracing down a seg fault, gdb may be dozens of times faster. ------------------------------------------------------------------------- Take Surveys.
