I can't localize it but I'm getting crashes using the latest Vim; the crash isn't happening consistently.

Are you able to reproduce with an asan build? (address sanitizer).

It should be a matter of uncommenting these lines in vim/src/Makefile
then "make clean ; make -j8":
SANITIZER_CFLAGS = -g -O0 -fsanitize-recover=all \
-fsanitize=address -fsanitize=undefined \
-fno-omit-frame-pointer
Then try to reproduce the bug. If asan finds memory issues,
it will output useful information on stderr, so it may be useful
to redirect stderr with: vim 2> asan.log

Unfortunately no, as I'm building under cygwin, but I was able to get a gdb backtrace:
