I'm still/also seeing this same test failing in version 15.0.3. I also notice in dmesg a large number of lines like "[18919551.656752] traps: simple-fail.cpp[26986] trap invalid opcode ip:55ea9c303805 sp:7ffe314cb8e0 error:0 in simple-fail.cpp.tmp9[55ea9c303000+1000]"; I don't know whether they're related to this test, one of the several that "expectedly failed", or something else entirely.
Again still/also seeing this test failing in version 18.1.8-r1, with "trap invalid opcode" lines like "traps: bounds.cpp.tmp[13788] trap invalid opcode ip:567184ab sp:ff812560 error:0 in bounds.cpp.tmp[56639000+e0000]".
