Summary0000408: Recursion in an out of memory situation
DescriptionHi,

this is related to 0000406, but this time without any catch. The driver tries to collect the trace, needs memory for this und so throws an error again, until num_error is 4, so that times_word[num_error] causes a segfault.

Greetings,
Gnomi

The backtrace:

I added a check in the error processing to recognize if it's called within a fatal (which is what happened here after the triple-error), and causes a double-fatal then.
