This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':


emacs -Q  to start
M-: (w32-shell-execute "open" "C:\\abc.ttt")

Emacs got killed by system because of segmentation fault. The file C:/abc.ttt
is just a text file with no system default associated program, and this should
make a w32-shell-execute error in the *Message* buffer. The following is the
mingw gdb backtraces.
