Offhand I do not know.  I think there are a few things that
could help us find out, though.

One would be to see the gdb session.  This would tell us
which libstdc++ is being loaded.

Another would be to attach the executable to the bug,
assuming it is small enough (if too large -- write a minimal
reproducer and attach it).  Then I could look at the DWARF.

I'm also curious exactly what options were used to build
the executable.  This can matter sometimes.
