Bug ID: 115705
Summary: dubious macro definition ‘__attr_dealloc_fclose’
[-Winvalid-imported-macros]
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: devdude2 at hotmail dot com
Target Milestone: ---
When I compile my code with c++ modules, I get this error, using gcc module
compiled headers, i.e. headers compiled like:
g++ -std=c++20 -fconcepts -fcoroutines -fmodules-ts -fmodule-header=system -x
c++-system-header random
I think cwchar and stdio define __attr_dealloc_fclose differently. Is this an
error and if so, can this be fixed, by making the definitions the same or
whatever?
Thanks
