Frequent enough that I feel the need to report this, stepping through a relatively simple app, mostly (I think) occurs when stepping OUT of a function before its last line (just an impression). This has been a frequent problem with RealStudio and I see it persists with Xojo. This is with today’s release (2018r2). Crash log:
