--- Comment #1 from Aaron Hill <aaron.hill at wdc dot com> --- Created attachment 51321 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51321&action=edit Add the empty 'foo.h' file used by 'test.cpp' This file contains a blank line, to allow me to attach it to this issue. However, the issue can also be reproduced with a completely empty file named 'foo.h'
