[lldb-dev] TestRegisterVariables broken on FreeBSD in the last couple of days

[Ed Maste]

A commit between r236411 (works) and r236595 (fails) broke
TestRegisterVariables on FreeBSD. I'll bisect the specific commit
later on but wanted to mention it in case the issue is obvious to the
author of the related chagnes:

..

(command="expr c", SBCommandReturnObject(0x801c27b00),

number.
