Hello Nils, "sometimes" sounds odd. That needs a difference on each run. Do you use a shell command to open the file (so that there is a timing difference)?
Some guesses for typical "sometimes" problems: - Do you have some pointer problem (use of an uninitialized one, unhandled error cases for functions that return pointers, ...)? Initialize all local pointer variables with NULL to get reproduceable results. - Are there some big stack variables (local arrays with sizes > 100 Byte)? Maybe your stack is too small and overflows.
