Bug ID: 67582 Summary: typeof(*p) * fails when p is void * Product: gcc Version: 4.8.4 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: vegard.nossum at gmail dot com Target Milestone: --- $ gcc --version gcc (Ubuntu 4.8.4-2ubuntu1~14.04) 4.8.4 $ cat voidptr void foo(void *p) { typeof(*p) *x; } I'd expect this to work as if 'x' was declared 'void *x' (which is legal). It works in C, but not in C++: $ gcc -x c -c - < voidptr && echo success success $ gcc -x c++ -c - < voidptr <stdin>: In function ‘int foo(void*)’: <stdin>:3:10: error: ‘void*’ is not a pointer-to-object type <stdin>:3:15: error: invalid type in declaration before ‘;’ token
