            Bug ID: 51027
           Summary: False-positives from scan-build clang 12
           Product: clang
           Version: 12.0
          Hardware: PC
                OS: Linux
            Status: NEW

I used scan-build with clang 12 and I believe that has a lots of
"false-positive".

The problem is with operator &.

Simplified example:

int main(void) {
     int v;

     foo(&v);
     printf("v=%d\n", v);  /* clang reports uninitialized var used here */
}

Of course, that code analyzed is more complex.
But I think that code that analyze the operator &, need be revised.

thanks.
