Bug ID: 98508
Summary: Sanitizer disable -Wall and -Wextra
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: awdawdawdawq123123 at gmx dot de
Target Milestone: ---

source file
1.cpp:
```
struct S
{
int a;
};
int main()
{
S s = S(s);
}
```
Compiling this by calling
g++ -Wall -Wextra 1.cpp
yields the warning:
```
1.cpp: In function ‘int main()’:
1.cpp:8:7: warning: ‘s’ is used uninitialized in this function
[-Wuninitialized]
8 | S s = S(s);
| ^
```
as expected. But when additionally using Sanitizers the call
g++ -Wall -Wextra -fsanitize=address,undefined 1.cpp
yields no warnings.
Attached is the source file.
