[Coin-lpsolver] Assertion failed in ClpSimplex

Tue Aug 23 21:56:57 EDT 2005

I've tried the latest version and it works. Thanks a lot - you guys are 
fantastic!
I checked the creation date of the earlier version of the file, the one that 
used to work before I ran into that problem, and it was from August 1st, so 
it was at least 3 weeks old when I checked it out, not 2 as I mentioned in 
my earlier email, which may explain why it worked when it wasn't supposed 
to. Somehow I thought it was more recent - sorry for the confusion.

Eric,
