Thanks!

Sorry, that was with the commit with message `New debugging command
'malloc-info''. I can say that this one existed before malloc_info was
introduced as i had seen it when bisecting the code.

I've now tested it with these commands and the build still fails.

first case:

git pull origin
git checkout testing
git reset --hard HEAD
git pull         # pulls from local master
make 2&> ../make-emacs-aug-15-head

This one fails with some segmentation fault.

seeing some warnings about newer source files being newer, i did
a make bootstrap (because make clean produced same errors) and it now
fails with different errors. this one seems to be even more weird.

make bootstrap 2&> ../make-bootstrap-aug-15-head

Before doing both of these, i had done a git bisect with the following
(with HEAD pointing to commit with `New debugging command
'malloc-info'')

git bisect start HEAD emacs-27.2-rc2 --

whoose output (after 1 compilation) was:

The merge base f5d7fb3a2dee3f9ae49151e3d01483aad7fb734b is bad.
This means the bug has been fixed between
f5d7fb3a2dee3f9ae49151e3d01483aad7fb734b and
[deef5efafb70f4b171265b896505b92b6eef24e6].



i don't know how much of it is relevant so decided to include it all.

Hope it helps.
