Re: Crash (assertion failed) in 21.2.44 - 100% reproducible
There seems to be a fencepost error in syntax.c. You could try
Vladimir Vukicevic's patch. This is (hopefully) being reviewed by
Matt Tucker now, and may not go in in its current form, but it might
help you get some work done.
Actually, now that I've looked at my code again, I realized that it wasn't
right -- the code does indeed need to know if the last matching comment element
came at the end of the passed in region, not the space before it. With
my patch, a visual glitch appears if you're typing a string in a font-locked
mode; the font-locking will lag one character behind the end of the string.
So, a more correct patch follows... I've been working with this for a while
yesterday with no crashes.
