<pre>Test case (prog.c):
inline void f()
{
static int x;
}
int main()
{
}
Compilation command line:
clang prog.c -Wall -Wextra -std=c11 -pedantic-errors
Observed behaviour:
No error message outputed. Only a warning message outputed.
Expected behaviour:
An error message outputed.
The program violates 6.7.4/3:
"An inline definition of a function with external linkage shall not contain
a definition of a modifiable object with static or thread storage
duration,
and shall not contain a reference to an identifier with internal linkage."
Since -pedantic-errors is used we should get an error instead of a warning.
Note:
GCC gives the expected error message.</pre>
