Hi All,
a very profound user has directed me to a Dat-file which crashes my Tool on makeDBs. I can reproduce this, and found the exact place where this ugly Bug is sitting and the reason why it is running wild.
The underlying reason is this: i create a buffer in memory and sometimes i read beyond the end of the buffer, which is not allowed. So the Operating-System gives a "NoGo!" with a 0xC0000005 "STATUS_ACCESS_VIOLATION".
A simple Programmer mistake.
What bugs me is as big fat this little thing is/was, why it it does not crash always and only on specific files. Hmm, lets see - comes time, comes knowlege.
What i like to say is - a bugfix is in progress.
