* [Bug c++/115216] New: operator auto() gets instantiatied too eagerly @ 2024-05-24 14:20 olaf.krzikalla at dlr dot de 2024-05-24 14:23 ` [Bug c++/115216] " pinskia at gcc dot gnu.org ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: olaf.krzikalla at dlr dot de @ 2024-05-24 14:20 UTC (permalink / raw) To: gcc-bugs https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115216 Bug ID: 115216 Summary: operator auto() gets instantiatied too eagerly Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: olaf.krzikalla at dlr dot de Target Milestone: --- Full example in: https://godbolt.org/z/3hG5fh1PW The example can be compiled either by commenting out line 24 or by swapping in line 8 for line 9. In any case line 25 works. Thus there is a difference between the terms "xx[1]" and "xx.operator[](1)". The error occurs with all recent gcc versions. It doesn't occur with any clang version. ^ permalink raw reply [flat|nested] 4+ messages in thread

Are you sure this is not a clang issue? To be honest I don't know. I have no idea, if a compiler is allowed to convert a type before applying a operator, if there is already such an operator available in the genuine class. Someone who knows the respective details in the standard is required. ^ permalink raw reply [flat|nested] 4+ messages in thread
