Bad parent pointer message in Saxon-HE-9.8.0-2
Saxon-HE-9.8.0-2 from maven issues a following text on output during compilation:
*** Bad parent pointer found in param at ...my.xslt#7 *** *** Bad parent pointer found in $e at ...my.xslt#9 *** *** Bad parent pointer found in $e at ...my.xslt#9 ***

Not sure whether it's an error of an info but it looks scaring. This does not happen with earlier versions.
P.S. Use any input.

The "bad parent pointer found" indicates that something has gone wrong usually while rewriting the expression tree during optimization. It's an early indicator of problems: very often the code recovers from the problem (the tree can be repaired) but sometimes a crash occurs later on as a consequence. So you're right, it's an indicator that there's a problem we need to fix.
