            Bug ID: 105608
           Summary: [13 Regression] ICE: in linemap_add, at
                    libcpp/line-map.cc:502 on ovito-3.7.1
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: preprocessor
          Assignee: unassigned at gcc dot gnu.org
          Reporter: slyfox at gcc dot gnu.org
  Target Milestone: ---

ICE initially observed on ovito-3.7.1 source code where
-DCOPYRIGHT="\"${long-string}\"" is used along with precompiled headers in
standard cmake setup.

Here is a 0-file reproducer:

# create empty files and dirs:
$ mkdir -p ph
$ touch ph/h.hxx.cxx
$ touch a.cpp

# trigger the bug:
$ /tmp/gb/gcc/xg++ -B/tmp/gb/gcc -Winvalid-pch -x c++-header -o ph/h.hxx.gch -c
ph/h.hxx.cxx
$ /tmp/gb/gcc/xg++ -B/tmp/gb/gcc
-DBUG=aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
-Winvalid-pch -include ph/h.hxx -o a.o -c a.cpp

gcc-12.1.0 does not seem to be affected. Only gcc-13 fails for me including
current master.
