Bug ID: 106309
Summary: ICE: error reporting routines re-entered
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: raffael at casagrande dot ch
Target Milestone: ---
I tried for over 2 hours to get a minimal test case but it is quite involved
and for now I give up. I've created a file with the preprocessed source using
`-freport-bug` and uploaded it to my dropbox:
https://www.dropbox.com/s/oxx299jhx7yi3b2/ccFsUsUT.out?dl=0 . Unfortunately the
file is 11Kb large so I cannot attach it here in bugzilla.
The error message that GCC produces is the following:

Please submit a full bug report, with preprocessed source.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

As far as I can tell, the file which I uploaded to Dropbox should contain all
the information which is necessary to reproduce the bug (e.g. command line and
precompiled sources).
If you need more information to reproduce the bug, please let me know.
