Bug ID: 116474
Summary: GCC somehow confuses "unsigned __int128_t" with a
nested function
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gabravier at gmail dot com
Target Milestone: ---
int main(){
unsigned __int128_t x = 0;
}
Compiled with -pedantic, results in the following warning:
<source>: In function 'main':
<source>:2:9: warning: ISO C forbids nested functions [-Wpedantic]
2 | unsigned __int128_t x = 0;
| ^~~~~~~~
<source>:2:29: error: expected '=', ',', ';', 'asm' or '__attribute__' before
'x'
2 | unsigned __int128_t x = 0;
| ^
<source>:2:29: error: 'x' undeclared (first use in this function)
<source>:2:29: note: each undeclared identifier is reported only once for each
function it appears in
It seems quite odd that a warning for a nested function is emitted here.
