Bug ID: 92732
Summary: Bit-field with std::byte as member type cannot be
initialized
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: klaus.doldinger64 at googlemail dot com
Target Milestone: ---
Since C++20 bit-field initializer are possible.
There seems to be a bug with std::byte an bit-fields.
struct Test {
std::byte a : 2 = std::byte{0}; // NOK
uint8_t b : 2 = 0; // OK
};
Compiling this with
g++ (GCC) 10.0.0 20191128 (experimental)
yields:
test93.cc:20:28: error: cannot convert 'std::byte' to 'unsigned char:2' in
initialization
20 | std::byte a : 2 = std::byte{0}; // NOK
| ^~~~~~~
| |
| std::byte
