Status: UNCONFIRMED
Severity: normal
Priority: P3

This constexpr variable definition
constexpr bool b = ( delete [][]{ return new int[2]; }(), true );
is accepted in Clang and MSVC. But GCC complains:
<source>:1:64: error: the value of '<anonymous>' is not usable in a
constant
<source>:1:56: note: '<anonymous>' was not declared 'constexpr'

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed,
Just to show it is unrelated to lambdas I defined it as a constexpr function:
constexpr auto g() {return new int[2];}
constexpr bool b1 = ( delete []g(), true );
