Bug ID: 96096
Summary: g++-10.1 silently ignores function violating const
instead of refusing to compile
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: agadethrowaway at gmail dot com
Target Milestone: ---
Created attachment 48842
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48842&action=edit
Minimal bug reproduction code
Attached code compiled with:
g++-10 (Ubuntu 10.1.0-2ubuntu1~18.04) 10.1.0
with compile line:
g++-10 Const_Violation_Silent_Error.cpp -o Const_Violation_Silent_Error
compiles whereas g++-9 (g++-9 (Ubuntu 9.3.0-11ubuntu0~18.04.1) 9.3.0) correctly
refuses to with error:
error: binding reference of type ‘dummy&’ to ‘const dummy’ discards
qualifiers...
Not only does this code compile when it should not, but it will simply quietly
never enter Modify_Object().
Copy of attached code:
struct dummy{
int int_param;
};
inline void Modify_Object(dummy &object){
object.int_param=0;
}
template <bool is_learning=true> void Templated_Function(){
const dummy R{0};
Modify_Object(R);
}
int main(){
Templated_Function();
}
