Ask the person who produced emacs.exe to tell you where he/she
downloaded libgcc_s_dw2-1.dll, and what are its size and time stamp.
Then look for that version of the DLL on that very site.

Greetings!

Basically, emacs has crashed on Win XP/7 for me, every time while I closed
it, since 23.x. I'm on the latest release, and being completely fed up now,
I finally decided to do something about it.

The fastest way to provide a context and background of my problem is to
provide this Stack Exchange link:
http://superuser.com/questions/576512/emacs-24-3-on-windows-7-does-not-close-properly


@Eli told me to get in touch here:

Thanks for any help you have on this one, people.

Best,
surio.

Hi,

AFAIK,  libgcc_s_dw2-1.dll is statically linked so it is irrelevant the
origin of the file.

I have experienced the same crashes and I can confirm two things:
- No crashes with gcc v3.x.x
- No crashes with gcc v4.5 sjlj

And this thread<http://sourceforge.net/mailarchive/message.php?msg_id=27481215>might
confirm the last point.

Now I am going to build with tdm-gcc-4.7.1-2
<http://tdm-gcc.tdragon.net/download>MinGW
sjlj <http://tdm-gcc.tdragon.net/download>, and test stability. If anyone
would like to test my binaries, please, let me know: I will be pleased.

HTH

Miguel.

A DLL can never be statically linked.

If you want to be sure whether or not your executables depend on that
DLL, use the "depends" tool, which you can download from the net --
just run it as in "depends emacs.exe" and it will show a window with
all the DLLs that the binary wants to load.  Or use objdump that you
already have, like this:

  objdump -x emacs.exe | fgrep "DLL Name:"

The latter only shows the names of the DLLs, not their absolute file
names.

If the above methods show that your binary depends on
libgcc_s_dw2-1.dll, you _must_ tell your users which one of them is
actually linked into the binary.  The "depends" tool will show you a
full path to the DLL which the binary will use, and the linker links
against the DLL which came with the version of GCC you used to compile
Emacs.  You should tell the users "get libgcc_s_dw2-1.dll from GCC
version 4.x.y that you find on this-and-that site".

Thanks.

I meant "every dependent compiled object included in the libgcc_s_dw2-1.dll
is statically linked"

Official emacs.exe, 2013-03-13 14:38, 9.031.038 bytes

objdump -x emacs.exe | fgrep "DLL Name:" yields

DLL Name: ADVAPI32.DLL
DLL Name: COMCTL32.DLL
DLL Name: COMDLG32.DLL
DLL Name: GDI32.dll
DLL Name: KERNEL32.dll
DLL Name: MPR.DLL
DLL Name: msvcrt.dll
DLL Name: OLE32.dll
DLL Name: SHELL32.DLL
DLL Name: USER32.dll
DLL Name: USP10.DLL
DLL Name: WINMM.DLL
DLL Name: WINSPOOL.DRV

So I asume there is no dependency on libgcc_s_dw2-1.dll.

I have always run emacs.exe with no libgcc_s_dw2-1.dll around.

Miguel.

A.k.a. "Emacs is statically linked with libgcc.a."

It can't be? A DLL can have exports but no imports.

It's a misunderstanding, probably mine.  I meant it cannot be
statically linked into a program that imports its functions.
