So, basically, you are saying that whenever you run "make X" through color, it will crash, but it will not crash in any other cases? Are you sure this is not a problem of color together with make (I had some strange problems that only occured when something was called by make, because the locale settings were messed up)? > > 2) If so, can you test it on the latest development release? > > I tried Graham's experimental 2.15.9 (from last week) and it worked fine at > first, but then I tried running it via gdb and it crashed with similar but > not identical backtrace as 2.14.2.

Hmm, do you have any example file where this appears (even if it's not minimal, for now it's just important that we can reproduce it somehow).
