Description
rr crashes immediately when trying to record anything under wine.

Research direction
Reproduce the crash while recording under Wine, then inspect src/AddressSpace.cc around line 1627 and the vdso-related address-space setup. Trace how recording handles systems without a vdso and identify the existing tests or recording path covering this case. Done means recording under Wine no longer aborts on the assertion.
