Hi Eike, Upon debugging IFS( 0, NA(), 1+0, "output" ) I came to the following preliminary conclusions: Before ScInterpreter::ScIfs_MS() is called, ScInterpreter::Interpret is called for argument '1+0' . That leads to a call to scInterpreter::CalculateAddSub( false ) and there the problem starts. 0 and 1 are popped and added, but after PushDouble( ::rtl::math::approxAdd( 0, 1 ) ) the raw stacktype is svError. Unfortunately most of the time I have only a machine with 4GB available for debugging, giving 5 minutes max before freezing, so the simple question what the raw stacktype is before PushDouble (when NA() is on top of the stack) will take
me up to an hour -which I don't have right now. Do you happen to know if in the case of a token on top of the stack of type svError (like NA()), this stacktype is remained when pushing new values/tokens to the stack? If that is the case, I wouldn't know a proper way to fix this, unless there are no use cases where this behaviour is desired. Any thoughts? Winfried |
