Bug ID: 87385
Summary: -Wmisleading-indentation shouldn't warn for labels
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: lennox at cs dot columbia.edu
Target Milestone: ---
Created attachment 44736

Test program that triggers the warning.
In the attached code, gcc gives a misleading-indentation warning for the label
in
if (input != NULL) free_subobj2(ret->obj2); FAIL3:
Since the if statement doesn't control whether a goto can actually go to the
label, I don't see how this indentation can be misleading.
$ gcc -Wall -c misleading-indentation-label.c
misleading-indentation-label.c: In function ‘alloc_object’:
misleading-indentation-label.c:46:2: warning: this ‘if’ clause does not
guard... [-Wmisleading-indentation]
if (input != NULL) free_subobj2(ret->obj2); FAIL3:
^~
misleading-indentation-label.c:46:47: note: ...this statement, but the latter
is misleadingly indented as if it were guarded by the ‘if’
if (input != NULL) free_subobj2(ret->obj2); FAIL3:
^~~~~
$ gcc -v
