njn, mccr8: do you know who could take a look at this ?

Comment 4

[Andrew McCreight [:mccr8]]

Maybe peterv? The crash looks like deeply nested recursion that exhausts the stack. Maybe this is a known issue.

Jonas worked on bug 1243337, which appears to be somewhat related.

I don't think there's any relation between this and bug 1243337. Other than that both are related to XSLT.

I wonder if the problem here is simply that we tear down txInstructions recursively, and that this creates a *really* long list of instructions, meaning that we simply run out of stack space.

Indeed, that's what I meant -- that you know about this code, not that you caused the crash :)  Sorry if that wasn't clear.
