--- Comment #6 from Bence Szabó <sbence92 at gmail dot com> --- > Ah, then it is not c++14 vs. c++17 ABI incompatibility, but some bug in > va_arg passing of such classes for mingw. It seems so. In t032 I got rid of the crashing tests (30, 56, 77, 80, 89, 100, 117, 134, 162, 171, 174, 191, 250 all of them are the second variadic test case) and the rest of the tests pass in t032. Same in t059: 2998, 2828 crash on 2nd variadic test the rest passes. Sorry for misleading bug report, I saw the same test cases fail as the mentioned reports, didn't know the reason is so different.
