Bug ID: 108295
Summary: Free label positions shouldn't be available outside
-std=c2x
Product: gcc
Version: 12.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: daniel.lundin.mail at gmail dot com
Target Milestone: ---
The new C23 features introduced in gcc 11.0.0 appears to be inconsistently
deactivated when picking some other version than -std=c2x.
The new C23 feature "Free positioning of labels inside compound statements"
appears to be active even with -std=c17 or the default gnu17 is picked. Unlike
other C23 features introduced in the same version 11 release, which are
correctly activated when using -std=c2x or otherwise inactivated.
For example gcc treats true/false as bool when activating -std=c2x but treats
them as int when older C versions are used. Free positioning of labels should
behave just in the same manner.
See attached example.
