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

[Bill Farmer]

I have used the Sysinternals process explorer, (http://technet.microsoft.com/en-us/sysinternals/bb896653), to determine the loaded dlls. Unfortunately it does not show a dynamic dependency tree. This shows that when a file is visited, the distribution version of emacs 24.4 loads zlib1.dll from the MinGW installation and libgcc_s_dw2-1.dll also from the MinGW installation. These are the only non-microsoft dlls I can see. The version of emacs 24.4 I built does not load any non-microsoft dlls. I have attached four text files showing the dlls loaded by the distribution version of emacs 24.4 when no files have been visited, the dlls loaded by the distribution version after a file has been visited, the dlls loaded by the locally built version of emacs 24.4 when no files have been visited, and the dlls loaded by the locally built version of emacs 24.4 after a file have been visited.

Hope this helps.

I have done a plain vanilla build of emacs 24.4 with my version of MinGW:

$ gcc -v
Using built-in specs.
COLLECT_GCC=c:\MinGW\bin\gcc.exe
COLLECT_LTO_WRAPPER=c:/mingw/bin/../libexec/gcc/mingw32/4.8.1/lto-wrapper.exe

mingw --disable-bootstrap LDFLAGS=-s CFLAGS=-D_USE_32BIT_TIME_T
Thread model: win32
gcc version 4.8.1 (GCC)

Configured using:
`configure --prefix=/d/c/emacs/build/usr'

I cannot reproduce the crash on exit problem with this version. It does not
include the libXpm.dll file.

Please try to find the DLLs loaded into the Emacs binary that does
crash.  I don't see any other way of finding out what caused it.
Somewhere on your system there is a DLL that depends on
libgcc_s_dw2-1.dll, and finding it is the way to solve this riddle.

Thanks.
