Default Software error or hardware error

I'm running mprime 25.11 64-bit on ubuntu 10.04 and today mprime crashed after finding a factor in P1. This has happened several times before, but since I was running in menu mode I got some extra info.
GuloGulo/Phenom_II_X6_1055T, M53619337 has a factor: 3068239623794576992633, AID: E7349195353FF153379E68612A21F119
 [Comm thread Jan 18 14:17]
 [Comm thread Jan 18 14:17] PrimeNet success code with additional info:
 [Comm thread Jan 18 14:17] CPU credit is 5.0082 GHz-days.
 *** glibc detected *** ./mprime: free(): invalid next size (fast): 0x0000000001f94d10 ***
 ======= Backtrace: =========
My machine is a Phenom II X6 1055T overclocked to 3.645GHz. It has been running with this overclock for months and I have never had any other errors than it crashing after finding a factor. Are these crashes still related to an overly ambitious overclock or could they be due to buggy software, libraries or mprime itself?

This is probably the infamous mprime P-1 segfault bug again, which has been around for ages.

OK, thanks for the quick reply! So there is nothing to do other than restart mprime? Is the bug that hard to track down?

I believe this bug is fixed in version 26. Try it.
