File to reproduce the bug

When using the -Os switch, I get the following error:

In file included from libc/inet/inet_ntoa.c:8:0:
libc/inet/addr.c: In function 'inet_ntoa_r':
libc/inet/addr.c:135:1: internal compiler error: in output_move_qimode, at
config/m68k/m68k.c:3160

The error disappears without the mentioned switch.

Command line and output:
