The code in red was not there, so for a line that would start with # comment the code tries to access buf[-1]. How peculiar that the error lingered there and was never causing troubles before my stack shifted as a result of arrays size growth.
BTW, the segfault happen on the consequent fgetc after the line with starting # hash mark.

Interesting.
Negative array indexes aren't specifically wrong per se, since you're allowed to do
Code:
int array[5]={1,2,3,4,5};
int *x=array+3;
x[-1]=2;
printf("%d\n", array[2]);
It's certainly not encouraged though.
Nothing to do with your stack though -- malloc() doesn't come from there.
Making malloc() larger may have ended up putting the block into a different heap, so the crashing code was more likely to hit invalid memory than to harmlessly nudge the end of your big array when loading a config file. Or could have been something else entirely. Difficult to tell.
