Bug ID: 79490
Summary: ICE when compiling CATCH unit testing framework header
Product: gcc
Version: 6.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vz-gcc at zeitlins dot org
Target Milestone: ---
I can't provide a self-contained example showing the problem, unfortunately, it
involves a (huge) header implementing the rather popular CATCH unit testing
framework which is available at
https://github.com/philsquared/Catch/releases/download/v1.7.1/catch.hpp
If you do get this header, the problem is easily reproducible however:
% g++ -v
Using built-in specs.

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-6/README.Bugs> for instructions.
The problem is, in fact, somewhere inside catch.hpp itself as it can also be
reproduced with just "g++-6 -c -fsyntax-only -Wall -x c++ -DCATCH_CONFIG_MAIN
catch.hpp", but this also gives an unrelated "#pragma system_header ignored"
warnings and doesn't give any extra information anyhow (it just points to the
end of the file).
Again, sorry for the lack of a SSCCE but I failed to find it by trying to
compile various parts of catch.hpp separately. Hopefully this report might
still be useful even in its current state.
