[Bug gdb/11321] New: Inferior crashes if user detaches while displaced stepping is in progress

["pedro at codesourcery dot com" <sourceware-bugzilla at sourceware dot org>]

GDB allows detaching while a thread is still executing in the
scratchpad, which leads to the inferior crashing shortly after having
been detached.

There's a post-single-step fixup step to adjust the PC (and possibly
other registers) in the displaced-stepping state machine, that is
just skipped if the user detaches exactly while a thread was in-progress
of doing an out of line step-over-breakpoint.
