Bug ID: 96155
Summary: "throw" that is not executed in constexpr function
fails to compile
Product: gcc
Version: 10.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: r-gcc at mail dot uk
Target Milestone: ---
This fails to compile on gcc trunk, while the same code compiles fine in clang:
constexpr bool foo()
{
for(int i = 0; i != 5; ++i)
{
if(i == 3)
return false;
}
throw 5;
return true;
}
this is the message I am getting:
error: expression ‘<throw-expression>’ is not a constant expression

Confirmed. Doesn't look like a regression.
