Enabling Checks for this warning class are disabled by default, and require the unnormalized C ASTs for the project. To enable them, add the following WARNING_FILTER rule and RETAIN_UNNORMALIZED_C_AST specification to the project configuration file.
RETAIN_UNNORMALIZED_C_AST = Yes
WARNING_FILTER += allow class="Multiple Statements On Line"
Note that retaining the unnormalized ASTs will increase the disk space used to store the project representation, and may make the analysis take longer.

Example

int lang_struct_multistmt(int a, int b){
    int i = a;
    int j = b;
    i++; j++;   /* 'Multiple Statements On Line' warning issued here */
    return i+j;
}
