Summary: Accepts ill-formed program with invalid scalar
initialization syntax.
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: anders.granlund.0 at gmail dot com
Target Milestone: ---
Test program (test.c):
int main()
{
int x = { { 0 } };
}
Compilation command line:
clang prog.c -Wall -Wextra -std=c11 -pedantic-errors
Observed behaviour:
No error message outputed. Only warning messages outputed.
Expected behaviour:
An error message outputed.
The initalizer 0 or { 0 } is valid according to 6.7.9/11, but not
{ { 0 } } .
Note:
Clang gives the expected error message for the program.
