Well another bug was fixed in 22.3.  You either had a hardware glitch or
ran across a rare GCD bug.  Your diagnosis was correct.  GCD returned a
factor, but when prime95 tried verifying it the factor did not divide the 
Mersenne
number.

All in all, don't worry about it.  The bug is rare enough that upgrading is not
terribly important.

The help file says this bug was fixed with version 20.5 concerning P-1 or ECM.

Mersenne: error result

2002-05-24 Thread Jud McCranie

I've been in GIMPS since before the first one was discovered.  Today I 
finished an exponent, and saw some stuff I haven't seen before.

After it completed, it said
M14776187 stage 1 complete ---transformations --- time
starting stage 1 GCD
stage 1 GCD complete
ERROR: factor doesn't divide N!
contacting server
etc.

What went wrong?

It looks like at the end of the L-L test, it did a GCD, thought it found a 
factor, but it wasn't a factor.

For a while during this exponent, I had quick user switching on with 
WinXP.  When I realized that prime95 was running twice as slow, I figured 
out that quick switching was causing two copies of primr95 to run.  Could 
that cause a problem?
