Lately Vim has been randomly crashing for me. After some bisecting I think
this patch may be the culprit.
At the very least, this patch causes Vim to crash when I resize the underlying
terminal very frequently while having a relatively large source file open (e.g.
Vim's own src/edit.c). If I revert the patch then I can no longer trigger this
particular crash.
The crash message is:
*** Error in `vim': double free or corruption (!prev): 0x00000000019fc270 ***
And a backtrace at the time of the crash:
