bug#29661: 27.0.50; emacs crashing on exchange-point-and-mark |
|

I've had a number of crashes today when running exchange-point-and-mark
on editing a particular file shortly after pasting in lots of lines from another
(v large) buffer. Probably replicable but atm hard to give an exact
recipe.
I'll keep the gdb session around in case it is needed.
Looking at gdb it appears to crash in delete_frame??
