Please include the complete backtrace with any bug report. See <https://gcc.gnu.org/bugs/> for instructions. Compiler returned: 1 This should likely give an error about using a trailing return type for a function with a declared return type other than a placeholder type. ^ permalink raw reply [flat|nested] 5+ messages in thread

Err, that would be bad now that I think about it (http://eel.is/c++draft/class.conv.fct#6). So I'd amend this to: it should probably give a reasonable diagnostic. :-) ^ permalink raw reply [flat|nested] 5+ messages in thread
