--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> --- (In reply to Tobias Burnus from comment #1) > Test case (seems as if the file name of the included file matters): It may be that the threshold for triggering the bug is length of token >= 32: libcpp uses location_t to store range information for tokens and expressions, and uses 5 bits of location_t to store short ranges. i.e. for tokens of up to 31 chars length, it can store them directly in location_t; for 32 and above it needs to use an ad-hoc location. > $ g++ TDICmds.cc > > TDICmds.cc:1:24: warning: #pragma implementation for > ‘create_defect_script_SCDBase.cc’ appears after file is included > #pragma implementation "create_defect_script_SCDBase.cc" > ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ FWIW, this token is 32 chars long (including the quotes), and so would have its location stored as an ad-hoc location.
