[saxon] Exception in thread "main" java.lang.AssertionError: **** Component reference is already bound

[David Carlisle]

I'm getting the following java error when processing a reasonably large
stylesheet (on any input) with saxon HE 9.8.

I am having some trouble cutting down the stylesheet to something
manageable to make a reproducible test case, but perhaps the stack trace
is enough if you know what you are looking for?

If not I will try harder tomorrow to isolate the example,

David

It's probably this one:

https://saxonica.plan.io/issues/3261

but not necessarily - it could be a different bug with the same symptoms.

It's not obvious from the bug entry but the source code triggering this is something like

xsl:choose
xsl:when test="$x=1".....
xsl:when test="$x=5".....
xsl:when test="$x=7".....
xsl:when test="$x=9 or $x=11".....

except that in place of the literals 1,5,7,9,11 there needs to be a reference to a global variable somewhere.

Actually, since you hit it on Saxon-HE, I suspect it is a different bug with the same symptoms.

Thanks. I can confirm this is gone with the 8.0.2 release.
