Warning: bytecode generation fails for try/catch
100%
Description
Warning seen while running the following expression in the latest saxon-ee 9.7.0.18:
let $x := try {
1
}
catch *
{
2
}
return xs:int($x)
Warning: Bytecode generation failed for main: (class: EE_main_01607683033, method: process signature: (Lnet/sf/saxon/expr/XPathContext;)V) Inconsistent stack height 1 != 2
See attached bytecode.
For 9.5, 9.6 warning is not returned but also fails bytecode generation (can be seen by adding debugByteCode="true")

Thank you for reporting the issue you have found.
Yes there is a bug in the bytecode generation which I am now investigating. The failure is detected which results in a warning message and the the compiler switching back to interpreted mode.

Bug fix applied in the TryCatch class. Here we call the the general InterpretedExpressionCompiler instead TryCatchExpressionCompiler. The TryCatchExpressonCompiler is not yet able to properly generate bytecode for try-catch.
