https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102204 --- Comment #3 from Ye Luo --- I tried today's main 3f0fcda37f58d4108feb67de08f181a32bcb6388. This issue persists. Any chance this will be resolved in 12 release?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102204 --- Comment #2 from Ye Luo --- User code has been written in mostly 5.0 fashion as 4.5 has too many restrictions. For most users, they only need a subset of 5.0 feature with up-to-date compilers and fully implemented 5.0 is not expected. Back to this issue, could the compiler just issue a warning instead of a full stop? In my case, bitwise copying of a struct is sufficient. Namely use the struct as if there is no virtual method. At least this unblock some potential users.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102204 --- Comment #1 from Jakub Jelinek --- That isn't a made up restriction, but the OpenMP 4.5 standard (and older too) explicitly requiring that "A mappable type cannot contain virtual members." OpenMP 5.0 doesn't have that restriction anymore, but removing it is part of significant other changes that need to be implemented on the compiler and library side and those haven't been done yet. AFAIK no compiler has full OpenMP 5.0 support yet.
