wrong location for tokens

Reported in the cppcheck forum: https://sourceforge.net/p/cppcheck/discussion/general/thread/9c0ae79e38/?limit=25

Example code:

int main()
{   
    char* ptr = 0;
#line 16 "main.sc"
{
#line 12 "main.sc"
    struct sqlexd sqlstm;
}
#line 16 "main.sc"
    strcpy(ptr, "bad");
}

Cppcheck reports this:

main.sc:21:12: error: Null pointer dereference: ptr [nullPointer]

The linenumber should not be 21 it should be 16.

Subsequent #line markers are ignored.

1: int main ( )
2: {
3: char * ptr = 0 ;
#line 16 "main.sc"
16: {
17: 
18: struct sqlexd sqlstm ;
19: }
20: 
21: strcpy ( ptr , "bad" ) ;
22: }
