            Bug ID: 22369
           Summary: Mingw linker crash with no-keep-memory
           Product: binutils
           Version: 2.28
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: martin.koegler at chello dot at
  Target Milestone: ---

I noticed, that a mingw x86_64 ld crashes, if no-keep-memory is used and it
gets passed an 64 bit ELF linux object.

$ cat t.c
=====
#include <math.h>
int _main(int argc)
{
return cosf(argc);
}
=====
$ 86_64-w64-mingw32-g++ -c t.c 
$ x86_64-w64-mingw32-ld -o t.exe  t.o /usr/lib64/libm.a  --no-keep-memory
