-TP option use works with XQuery and Saxon 10.1 HE but gives error ArrayIndexOutOfBoundsException with EE

Added by Martin Honnen over 4 years ago

I was trying to use the -TP option, strangely for Saxon 10.1 HE it works with XQuery but for EE I get an error

java.lang.ArrayIndexOutOfBoundsException: Local variable $vv:v0 uses slot 0 but no slots are allocated on the stack frame

Full command line and error output:

Fatal error during query: java.lang.ArrayIndexOutOfBoundsException: Local variable $vv:v0 uses slot 0 but no slots are allocated on the stack frame

The code runs fine with EE if I don't use the -TP option.

I will attach the query.

With EE 10.0 I get a similar stack trace when trying to use -TP, for EE 9.9 the option works flawlessly.

Thanks, we'l look into it. Likely cause is that the trace instructions injected into the expression tree are confusing the optimizer in some way.

Problem reproduced. There's a lot of function inlining revealed by the -explain output, and that would appear to be where things are going wrong.
