[Bug: 21.5-b27] [CRASH] (file-name-directory "1:")

================================================================ 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 * 0: nnml:Enote * 0: nnml:FM4-Community 1: nnml:Gnus 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!
