This happens when I was going to discover something for the first time.

The problem is that researchListPos is -1


gdb) output tech
(technology_t *) 0x0
(gdb) output researchListPos
-1

The problem is that the 'bolter' which I was going to discover does not seem to be in the tech list...

Thanks for this bugreport. Apparently we introduced this segfault when fixing an other one. :-) I&#039;ve commited a fix in r6201.
