Bug ID: 98682
Summary: g++ allows goto inside statement expr
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nbkolchin at gmail dot com
Target Milestone: ---
The following obviously incorrect program compiles without error under g++:
#include <stdio.h>
int main(int argc, char** argv)
{
goto L_bug;
printf("%s, %s %s\n", "Hello", ({ L_bug: ; "world!";}), "What?");
}
gcc produces error: "error: jump into statement expression".
Tested under gcc versions: 6.3.0, 7.5.0, 10.2.0.
This behaviour contradicts with documentation: "Jumping into a statement
expression with goto or using a switch statement outside the statement
expression with a case or default label inside the statement expression is not
permitted."

I think this is a dup of bug 772.
