[SR-Users] Child process exited by a signal 11

Um....
This makes perfect sense. 
Enhanced my understanding about memory allocation, too.
Thanks Alex.

That is logical, and is probably true in many cases.

However, it all depends on the memory allocation strategy used by the program internally, as well as on the operating system side. For instance, more logging could trigger a larger buffer allocation or different fragmentation, which could serve to mask the memory bug by not creating the circumstances that lead to an acute access violation, or not creating them in the same place or as soon.
