            Bug ID: 108332
           Summary: dynamic link libstdc++ with win32 thread model's gcc
                    for windows native toolchain would cause .rdata_r:
                    section below image base
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: unlvsur at live dot com
  Target Milestone: ---

g++ -o helloworld helloworld.cc -Ofast -std=c++23 -s -flto -march=native
-I../../include -static

//ok no issue

g++ -o helloworld helloworld.cc -Ofast -std=c++23 -s -flto -march=native
-I../../include
d:/x86_64-windows-gnu/x86_64-w64-mingw32/bin/../lib/gcc/x86_64-w64-mingw32/13.0.0/../../../../x86_64-w64-mingw32/bin/ld.exe:
helloworld.exe:.rdata_r: section below image base

Do not know whether it is an issue for mingw-w64 or libstdc++

This seems like a binutils ld bug rather than a libstdc++ bug ...

cygwin was improved here:
https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=801120c1f402f9b0f72b5a231bf9e1cf82614cac

It might be the case mingw linker script is broken ....

This is mingw-w64, not newlib-cygwin

I think he's suggesting that we have to apply the same solution to mingw that
Corinna applied to Cygwin.

I doubt this is the issue with ld linker. More likely to be a libstdc++ issue.
