Bug ID: 101176
Summary: valgrind error for
c-c++-common/builtin-has-attribute.c
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
For the gcc testsuite file c-c++-common/builtin-has-attribute.c
and a recent build of gcc trunk with valgrind, I get:
./c-c++-common/builtin-has-attribute.c:31:32: error: ‘foobar’ undeclared (first
use in this function)
31 | b = __builtin_has_attribute (foobar, aligned); /* { dg-error
".foobar
. \(undeclared|was not declared\)" } */
| ^~~~~~
==104199== Use of uninitialised value of size 8
==104199== at 0x16EDF70: htab_find_slot_with_hash (hashtab.c:654)
==104199== by 0x169B7CD: get_combined_adhoc_loc(line_maps*, unsigned int,
sou
rce_range, void*) (line-map.c:208)
Since this valgrind error is for C code with errors in it, I think
this is reduced priority.
