Hi,

Just updated after the hols and 64bit build on Ubuntu 14.04 is now crashing using nerdtree and opening a new file in a split window.  Looks like an invalid free() processing autocommands but I'm in the early stages of tracking it down.

Is anyone else seeing the crash and already working on it?  Don't want to waste my time if it is already on someone's radar.

TTFN

Mike

Can you give the exact steps so we can reproduce?

Try running Vim with valgrind or asan, as described
in this comment:

https://github.com/vim/vim/issues/5410#issuecomment-569516803

And reports memory errors from valgrind or asan.

Best to try asan first, as valgrind gives noise when using python interpreter.
asan is also faster.

Regards
Dominique

Hi,

Pinned down the patch that introduced the crash as "8.2.0056: execution stack is incomplete and inefficient".  I'll have a go with asan tomorrow unless someone else works it out first.

TTFN

I'm not aware of such a problem. Perhaps valgrind can tell you where it
happens.

FTR the crash has been fixed by patch 96.  Nothing more to see, move along now.
