Bug ID: 90807
Summary: Wrong debug message
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
My gcc is 10.0.0, and my code is:
void f() {
union {
typeof
(
(
{
unsigned long __ptr;
(int *)(0);
}
)
)
__val;
};
}
gcc rejects it with the following message:
x86-64 gcc (trunk)
1
<Compilation failed>
No Results
x86-64 gcc (trunk)
- cached
#1 with x86-64 gcc (trunk)
<source>: In function 'void f()':
<source>:5:2: error: statement-expressions are not allowed outside functions
nor in template-argument lists
5 | (
| ^
Compiler returned: 1
The message seems to be wrong, since the statement-expression here is inside a
function and not inside a template-argument-list.
BTW, the code does not violate any of the rules in
https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html). Clang accepts the
code. Do you intend to allow statement-expressions inside function-local type
definitions or not.
