Jeff,
Thanks a lot! I will do the things you've suggested shortly. Meanwhile, out of
curiosity, I am attaching a good recog.i (built with vectorization enabled,

This looks like it was caused by an extension which was removed in 4.2.0.
Also I think there might be a dup of this bug filed already.
That would be PR 28088.

GCC mangles foo::localstruct::f as '_ZZ3foovEN11localstruct1fEv'.
According to the C++ ABI (see especially the third example in
