Bug ID: 123146
Summary: Improve wording for "'use of uninitialized value
'<return-value>' here"
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
Target Milestone: ---
After r16-6063-g0b786d961d4426 the analyzer now complains about paths that
"fall off the bottom" of non-void-returning functions, albeit with this
message:
../../src/gcc/testsuite/gcc.dg/analyzer/compound-assignment-2.c:23:1: warning:
use of uninitialized value ‘<return-value>’ [CWE-457]
[-Wanalyzer-use-of-uninitialized-value]
23 | } /* { dg-warning "leak of 'aw2.ptrs.0.'" "leak of element 0" } */
| ^
‘test_2’: events 1-3
18 | test_2 (void)
| ^~~~~~

| (1) region created on stack here
| (2) capacity: 16 bytes
......
23 | } /* { dg-warning "leak of 'aw2.ptrs.0.'" "leak of element 0" } */
| ~
| |
| (3) ⚠️ use of uninitialized value ‘<return-value>’ here
We should improve the wording for this case (and perhaps use a different
command-line option)
