Re: [basex-talk] Bug? Local variable has not been allocated a stack frame slot
Bummer, it's very tricky to isolate/repro in a minimal case. At the moment don't have the time to pursue this further. Maybe later. --Marc On Wed, Apr 8, 2015 at 2:27 PM, Marc van Grootel marc.van.groo...@gmail.com wrote: Sure, I'm going to try this evening.

[basex-talk] Bug? Local variable has not been allocated a stack frame slot
Hi, I have hit something which is related to Saxon XSLT. The XSLT in question runs fine standalone (via Oxygen).

Hi Marc, I would tend to say it's a Saxon issue. We have no Saxon-specific code in our XSLT functions, and the complete stack trace seems to indicate that something is going wrong in Saxon. – However, I can also have a look at this if you send me an SSCCE for that bug.
