I don't think so. It looks like the illegal instruction is happening in
/usr/include/c++/9/ext/new_allocator.h:119 (I'm not really familiar with
c++ internals and might be wrong, though).

Anyway, this "illegal instruction" might point to a miscompiled, or
wrongly cpu-optimized stanard library.

I'd file a bug with this information in the openSUSE bugzilla, so that
the toolchain team can have a look.
