Bug ID: 90382
Summary: internal compiler error: in
linemap_macro_map_loc_to_exp_point, at
libcpp/line-map.c:1061
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: sbergman at redhat dot com
Target Milestone: ---
I encountered this ICE with recent GCC trunk with
#include "boost/spirit/include/phoenix.hpp"
but could only strip it down to the following reproducer that still includes
some boost/preprocessor/ include files (from boost-devel-1.69.0-6.fc30.x86_64
on Fedora 30 in my case). The failure was not reproducible with -E
preprocessed sources.
