Bug ID: 88392
Summary: Incorrect error message when using bitfields in void
*pointer
Product: gcc
Version: 8.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: frederic.pet...@univ-grenoble-alpes.fr
Target Milestone: ---
Hello,
the following (arguably quite strange) structure declaration outputs a somewhat
misleading error message on a x86_64 host (Thanks to Mathieu Barbe for pointing
it to my attention):
$ cat b.c
struct {
void *v:44;
} z;
$ gcc -Wall -Wextra -fsyntax-only b.c
b.c:2:13: error: bit-field ‘v’ has invalid type
void *v:44;
^
b.c:2:13: error: width of ‘v’ exceeds its type
The first message is fine, but the second is I believe erroneous as sizeof
(void *) is 8 on that machine. A bit misleading but not a big deal, though.
All the best,
Frédéric
