I have a source where some weird condition unstably produces the Segmentation Violation.
The error could disappeared or be moved into different place by adding/removing some line of code (some printf() and additional declaration/definitions.)
By 'dbx’, I see how some variable changed unexpectedly into impossible values.
I see the resulted change when the variable is used, but I can't catch when it is happening (the variable change itself!)
It still could be a logical error in code, but working on that problem already couple weeks (before last changes it works fine when I have removed all debug-statements) I start to think about some extreme situation, related to system (maybe our, maybe the standard one.)

I have reviewed today the code with expanded all macros (thanks to JohnGraham for advise how to do that!) and I see some line after that reach 4096 characters long and I am not sure by now if the line is braked in code or it is done by the editor (I use UltraEdit )
Just realized, that it is right - the lines are braked by the editor and actually, in code they are longer: the one I have reviewed now is 4096+1537 = 5633.
There are some code lines, consist of couple of 4096-chars lines.

Therefore, I've been thinking if a long code line in some situations comes across the processing memory, having the debug option is on...

(... Writing, I've thing that the memory for code and the processing memory used in different time... and debugging information does not include the '-E'-code lines, but just references to the original source file..., but ... not completely sure if the so long lines of code is not a reson of that error ...)

Therefore, I've asked this question trying to review any possibility for that error...

If you would have some idea or advise what else I could do to catch the error, I will appreciate to hear it very much!
