------- Comment #1 from tromey at gcc dot gnu dot org 2006-12-29 03:28 ------- This happens because destringize_and_run calls cpp_push_buffer. The new buffer has a non-null 'prev'; do_pragma_system_header checks for prev==NULL to determine whether the directive is in the primary source file.
I'm testing a patch for this. -- tromey at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tromey at gcc dot gnu dot | |org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2006-12-29 03:28:29 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28165
