This was introduced in r117806 (alloca doesn't like negative arguments).

Fixed in trunk revision 117918.

The crash does not happen with the -Q option, only with my init
file. The recipe to make the crash is

C-h
i
m
Elisp
RET

Actually, it is not the Elisp manual as such that is problematic, but
any manual bundled with Emacs causes the crash, while other manuals are
OK. I suspect that the difference is because of the gzipping of these
bundled manual.

I tried to start Emacs from gdb (the latter started from an MSYS
console) but then I got that xbacktrace is not supported. And the crash
happened earlier, just with `C-h i'.

I think I should try with a simpler init file --- to find the smallest
thing causing the crash, but I have not yet done this investigation.
