Hello,
i'm using BC(4.1.4) to compare files via script. This script is called via a Program in a loop to get many compare results.
Normally it works well, but sometimes it throws an error. I think this error only occurs if the script is executed very often by the Program-Loop (~2000-3000 times).
the exception message: "Access violation at address 00000000013AC326 in module 'BCompare.exe'. Read of address 0000000000000084."
Question: What could be the problem? Maybe too much RAM is reserved and blocked?
I can't send the whole bug report its too long for the forum and the size of the txt is too big for the limited attachment size.
Just a cutout:
