Bug ID: 67088
Summary: Incorrect location of error on invalid type used in
bit-field declaration
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: chengniansun at gmail dot com
Target Milestone: ---
I define a struct with a bit field but declare it as "double". Gcc emits an
error on it but point to the start of the line, not the location of this
attribution declaration.
$: cat t.c
struct S {
double d; double s:1;
};
$: gcc-trunk -c t.c
t.c:2:3: error: bit-field ‘s’ has invalid type
double d; double s:1;
^
$: clang-trunk -c t.c
t.c:2:20: error: bit-field 's' has non-integral type 'double'
double d; double s:1;
^ ~
1 error generated.
$: gcc-trunk -v
Using built-in specs.
