Summary: C++ compiler fails to build for m68k-linux-gnu
Product: gcc
Version: 14.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: wbx at openadk dot org

Hi,
I am trying to cross-compile gdb for m68k (68040).
In the second stage gcc fails to build libsupc++ with following error:

Is this a gcc bug or has it something todo with glibc 2.41 or binutils 2.43.1?
This also happens for gcc 13.3.0.
Any help is appreciated.
