--- Comment #2 from Alan Hayward <alan.hayward at arm dot com> ---
The the first call to vectorizable_condition (the check stage) succeeded, but
the second call (the build stage) failed, causing an assert.

Reproduced with head r230297

When updated to latest head, r230596 , issue is no longer present.

Looking at changes in the vectorisor, there have been some vector bool changes,
r230309. The vector bool work previously clashed with my work, so I suspect
those changes have fixed it.
