Bug ID: 100788
Summary: Internal compiler error related to #line macros(?)
Product: gcc
Version: 11.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: sebastian-gcc at sipsolutions dot net
CC: marxin at gcc dot gnu.org
Target Milestone: ---
I first thought this might have been the identical issue as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95847 as it seemed similar. There
is also https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96353, but I do not think
this is the same issue.
We have a large file in NumPy which generates compile errors on gcc 9+ (gcc 8
seems fine as far as I can tell). The issue on NumPy is:
https://github.com/numpy/numpy/issues/18529 (It is not a major issue, but I
fear it might get problematic for our coverage tools when they stop using GCC
8, which I think they are still using.)
I have attached the source file that generates the issue. Note that it is
generated by a custom templating language, so I can't fully rule out that the
inserted `#line` directives are incorrect.
The one clear thing I know is that removing all `#line` directives makes the
coverage compilation successfully.
I expect you may need more information, but am not sure how to best provide it,
considering that the file is part of the larger project.
The error/log is (this one with gcc (Debian 10.2.1-6) 10.2.1 20210110, but
confirmed on a gcc 11:
