Bug ID: 110408
Summary: gcc 13 crashes with %rename in specs
Product: gcc
Version: 13.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: brjd_epdjq36 at kygur dot com
Target Milestone: ---
According to https://gcc.gnu.org/onlinedocs/gcc/Spec-Files.html
if I apply this instruction to redefine only a part of the specs file:
%rename lib old_lib
*lib:
--start-group -lgcc -lc -leval1 --end-group %(old_lib)
,it is not necessary to change the whole specs file.
Still, in gcc 13 it crashes and returns this error:
g++-13: fatal error: specs file malformed after 35 characters
compilation terminated.
35 characters is the position after the last character in the old_lib string.
I test it with an older compiler gcc 4 and it is wonderful, no error.
I suppose that this manual is not updated to work in gcc 13 and there are
changes in the syntax.
