            Bug ID: 111170
           Summary: Malformed manifest does not allow to run gcc on
                    Windows XP (Accessing a corrupted shared library)
           Product: gcc
           Version: 13.2.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---
            Target: i686-w64-mingw32 @ Windows XP
             Build: i686-w64-mingw32 @ Windows 10

I wanted to build gcc 13.2 with intention to run it on an old Windows
XP/Pentium-M machine. My build environment is MSYS2/MinGW32 @ Windows 10.
Everything went fine and I could run resulting binaries on the build machine
under MinGW32 terminal. However when I tried to run them on the target mach=
ine,
I got "bash: ./mingw-gcc/bin/gcc: Accessing a corrupted shared library". Af=
ter
a few days of heavy fight I found out that this is due to malformed manifest
embedded in some (not all!) gcc executables. Newer version of Windows are m=
ore
forgiving and can tolerate malformed manifests while Windows XP is not; tha=
t's
why I could run freshly built gcc on my Windows 10 box. Using a resource ed=
itor
I have replaced malformed manifests with a default one (taken from
https://packages.msys2.org/base/mingw-w64-windows-default-manifest) and now
everything runs fine on XP.

The malformed manifest comes from
https://gcc.gnu.org/git/gitweb.cgi?p=3Dgcc.git;h=3Dd11e088210a551235d3937f8=
67ee1c8b19d02290
related to PR108865. I think the proper solution is to merge default manife=
st
from MSYS and the one mentioned in the diff above.=
