Gilbert,

I obtained the regular expression and string from the core-file on which the 
regexec(3) call was seg-faulting. I tested them both with the regexec(1) 
utility. They worked fine 10,000
times. I don't know what's causing your problem.

As farfetched as it sounds, I have seen forum entries indicating that the 
regular-expression module in the GNU library has bugs. It seems unlikely, but 
perhaps this is the problem.

Are Weather and Weather2 the same as Weather3?
