Comment 4 for bug 1495975

Hi Nishita,

The bad news is that I’m not able to reproduce your error on my computer (even with all debug flag activated).

I’ve take a look at the line/file that you mention:
>> (in file 'matrix1.f', at line 109)

and this is kind of impossible to have an overflow on that line.
Could you check the following two file:
SubProcesses/P0_gg_xksixksig/maxamps.inc
and check which value is written for MAXAMPS (second line of the file, in my file I have 12)
and in SubProcesses/P0_gg_xksixksig/matrix1.f at line 28.
the value given for NDIAGS (I have 12 as well).

The only explanation to the bug that you report is that the second number is larger than the first one.
But since those files are created by python it is really weird if you would have different value than me for those.

So in all cases in completely in the dark about that bug.

Cheers,

Olivier
