Problem with WinDbg .expr command

OSR_Community_UserOSR_Community_User Member Posts: 110,217
I came across a problem in WinDbg (both 4.0.18 and 6.0.7 versions) when
using .expr command. I am not able to set a breakpoint when I previously set
expression evaluator to C++ (using ".expr /s c++" command). Additionally, if
I restart WinDbg session, saved breakpoints are not restored because of
setting evaluator.
