Hi there,
I got a problem on pilot list, which crashes fgfs several seconds after the
dialog shows up.
The crash dump and some info on gdb below shows Null pointer assignment
(iter->second = NULL).
This problem happens with fgfs as of June 13th, but doesn't happen with one as
of May 19th,
so some changes between these two dates have something to do with this problem.
I've started investigating on this but not yet reached the real cause.
Does anyone knows anything on this?
FYI, I attached the excerpt cvs logs of FG and SG at the bottom (from May 19th
to June 13th)
