================================================================
Dear Bug Team!
Reproducible in vanilla, with following configuration.
Just evaluate
(file-name-directory "1:")
in the *scratch* buffer (without any unsaved autobiographies or other
work close to your heart).
This gets triggered "randomly" by following ffap configuration of
mine, when I use
C-x C-f (find-file-at-point)
; 2006-09-17
(require 'ffap)
; C-x C-f (find-file-at-point)
; which I learned about in c.e.x is quite handy!
(ffap-bindings)
It probably happens when using C-x C-f in a *Group* buffer, with
content like ...
1200: nndraft:drafts
* 0: nnml:ALD
* 0: nnml:AMEX
* 0: nnml:ASIC_FPGA
* 0: nnml:DNS
* 0: nnml:EngineeringIT

Apparently, wcslen naively dereferences its const wchar_t *ws argument
without checking for a null pointer:
wcslen(const unsigned short * 0x00000000) line 39 + 5 bytes
XEMACS! 01206394()
I've traced this down to src/intl-win32.c whose functions have blind
faith in pointers they are being passed.
sysdep.c also contains versions of various wchar functions without
proper argument checking.
Still investigating ...
Best regards!
Adrian
