Bug ID: 82310 Summary: Odd regression in g++-6.4.0 with a variable named major Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: dflogeras2 at gmail dot com Target Milestone: --- After upgrading to gcc-6.4.0, one of my regression tests fails to compile. I boiled it down to the following simple code which fails to compile, claiming that "major" was not declared in this scope. If I change that variable name to something else (maj), it works. #include <stdexcept> #include <stdint.h> int main() { const uint32_t minor( 0 ); { uint32_t file_minor = 0; if( minor!= file_minor ) throw std::runtime_error( "version error" ); } }
