Long version:
I have a (relatively simple) program that has been running
flawlessly 24x7 the last 4 years.
[...]
The most intriguing part is that, under the test conditions,
FindInvalidUTF8Character is only given pure ASCII strings, so it
should never enter the branches where it checks p[1], p[2] or p[3],
so I'm really puzzled.
Me too. Nevertheless, I fixed FindInvalidUTF8Character.
Thanks.
Meanwhile the program has been running all the week-end without
hanging the system.
Well, it hanged again today, with no call to FindInvalidUTF8Character in
sight. I hoped I nailed it but it was a red herring :-(
Note that the version that worked through the week-end was compiled with
gtk1, the one that hanged today with gtk2 (but I think that's another
red herring).
I'm re-resting now the gtk1 version to see what happens.
Well, I think (though I cannot be sure until I had the system running
more time) that I found a solution: I reverted the development
environment to the same situation as 2 years ago (when I made the last
successful modification to this program), i.e:
fpc 2.0.4 (with a couple of patches so that the ide works with gtk2 even
if the final program is for gtk1)
lazarus svn 11880 (I think I used an earlier version at the time, but I
couldn't determine the exact version, this one is one of the latest
compiling with fpc 2.0.4 and working with the ide compiled for gtk2)
If this works (crossing fingers), I'm *not* happy with the solution,
since I'd really like to know what happened to make linux hang hard
using a newer fpc and a newer lazarus (I cannot say which one is the
culprit).
This is running on an epia board, though it's a nehemiah and it
shouldn't be affected by the cmov issue (if that could be the cause of
the problem, which I doubt).
Bye
