I can reproduce this example with a similar state of -current on i386.
I've also seen other, probably related examples with other packages. In
one case (with libfilezilla, IIRC), it also happened with a much older
state of -current that still had GCC 7.4, so the general issue may
predate the current compiler version. The commonality I've seen is that
it's always C++ code that triggers it.
