Bug ID: 90830
Summary: A not fully fixed ICE?
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
The bug report fixed a ICE:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70449
template <int I>
constexpr int f ()
{
enum E { a = f<0> () };
return 0;
}
Given the code, gcc 10.0.0 rejects the code:
<source>: In instantiation of 'constexpr int f() [with int I = 0]':
<source>:4:21: required from here
<source>:4:21: error: 'constexpr int f() [with int I = 0]' called in a constant
expression before its definition is complete
4 | enum E { a = f<0> () };
| ~~~~~^~
<source>:4:8: error: enumerator value for 'a' is not an integer constant
4 | enum E { a = f<0> () };
| ^
Compiler returned: 1
However, I tried clang and icc, and both compilers accept the code. Is the bug
fully fixed?
