Saxon

The attached stylesheet applied to any document produces "true" when bytecode generation is off and an empty sequence when it's on. Returning an empty sequence as a result of functions f1 and f2 violates their return types. The bug can be bypassed changing the 'eq' operator to '='.

Thanks for reporting it. We'll look into it. You may not hear from us for a few days as we're all away at W3C meetings this week.

Bug fixed and committed to bytecode, which will be available in the next maintenance release.

Bug closed. Fixed in Saxon maintenance release 9.4.0.7
