bug#19181: 24.4; 24.4.1 libgcc_s_dw2-1.dll crash on exit

[Bill Farmer]

Hi

In the file ~/etc/PROBLEMS is a mention of potential problems with
libgcc_s_dw2-1.dll. I have an installation of MinGW on this windows
machine which is in my PATH, as do many other emacs users, I would
imagine. If I rename libgcc_s_dw2-1.dll in my MinGW installation, emacs
works fine and does not crash on exit. However, this breaks MinGW. So I
checked for mentions of libgcc in the emacs executables:

Bill@CYNTHIA /d/Images/emacs/emacs-24.4
$ find . -name "*.dll" -exec strings -f {} \; | grep libgcc
./bin/libXpm.dll: libgcc_s_dw2-1.dll

Bill@CYNTHIA /d/Images/emacs/emacs-24.4
$ find . -name "*.exe" -exec strings -f {} \; | grep libgcc
./bin/addpm.exe: libgcc_s_dw2-1.dll
./bin/ctags.exe: libgcc_s_dw2-1.dll
./bin/ebrowse.exe: libgcc_s_dw2-1.dll
./bin/emacs-24.4.exe: libgcc_s_dw2-1.dll
./bin/emacs.exe: libgcc_s_dw2-1.dll
./bin/emacsclient.exe: libgcc_s_dw2-1.dll
./bin/emacsclientw.exe: libgcc_s_dw2-1.dll
./bin/etags.exe: libgcc_s_dw2-1.dll
./bin/runemacs.exe: libgcc_s_dw2-1.dll
./libexec/emacs/24.4/i686-pc-mingw32/cmdproxy.exe: libgcc_s_dw2-1.dll
./libexec/emacs/24.4/i686-pc-mingw32/ddeclient.exe: libgcc_s_dw2-1.dll
./libexec/emacs/24.4/i686-pc-mingw32/hexl.exe: libgcc_s_dw2-1.dll
./libexec/emacs/24.4/i686-pc-mingw32/movemail.exe: libgcc_s_dw2-1.dll
./libexec/emacs/24.4/i686-pc-mingw32/profile.exe: libgcc_s_dw2-1.dll
./libexec/emacs/24.4/i686-pc-mingw32/update-game-score.exe: libgcc_s_dw2-1.dll

Every executable file in the emacs version 24.4 windows installation has
a reference to this dll. I don't think this problem is fixable without
building my own version from source. I use the binary version to avoid
this. I will have to revert to the previous version intil someone does a
build without this problem.

Regards
Bill
