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
