Date: Tue, 13 Oct 2020 11:17:13 +0000 [thread overview] Message-ID: <bug-97401-4@http.gcc.gnu.org/bugzilla/> (raw) https://gcc.gnu.org/bugzilla/show_bug.cgi?id=97401 Bug ID: 97401 Summary: static int has a default value? Product: gcc Version: 11.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: tangyixuan at mail dot dlut.edu.cn Target Milestone: --- Hi, the following code declares a static Integer without specific value. Usually, it will has a default value '0', and thus 'b[a]' could be declared as b[0] perhaps. However, gcc rejects it while clang accepts. $ cat s.cpp template<typename> struct A { static int a; char b[a]; }; $ g++ -c s.cpp s.cpp:3:10: error: size of array ‘b’ is not an integral constant-expression 3 | char b[a];
