with MSVC's 'cl.exe', I often get:

I can't reproduce that on Ubuntu x86 or x86-64. I built a test case this
way:
for dir in d e; do
(mkdir $dir &&
cd $dir &&
for i in $(seq 8000); do
echo $dir$i>$i
done)
done
and "diff d e >f" worked just fine. Do you have a reproducible test case?
From where the allocation fails, I've no idea since Gnulib is so
unfriendly telling where this occurs. Is there really no
xmalloc_die() with some more useful messages than this? Yikes!
When you run out of memory, bad things happen pretty much everywhere.
Too bad Microsoft gives you a bad backtrace.
You might try running the leak detector though to be honest I've not had
much luck with that.
Another possibility is to try to find the commit that introduced the
problem, if it's reproducible.
