Bug ID: 86253 Summary: N3639 array of runtime bound Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: zhonghao at pku dot org.cn Target Milestone: --- The code is as follow: int main(int argc, char** argv) { int x[1][argc]; [&x](int i) { x[0][i] = 0; }(5); return 0; } clang++ accepts the code, but g++ produces error messages: capture of variably-modified type ‘int [1][argc]’ that is not an N3639 array of runtime bound because the array element type ‘int [argc]’ has variable size I thought that this is a bug in clang, and reported it to https://bugs.llvm.org/show_bug.cgi?id=37843 However, Richard Smith told me that clang++ can produce this message, since clang++ has a feature that GCC's extension lacks. Does gcc have plan to implement that feature?
