I've just migrated to FB 2.1.3 and have experienced this bug with a UDF function that worked fine on Interbase (6.1, 2007). I get the error "The code attempted to access a virtual address without privilege to do so" and the server terminates abnormally.

From what I can tell, the bug tracker says that it's fixed in 2.1.4 but I cannot find where it can be downloaded.

I did find somewhere that adding "isMultiThread:=true" to the udf may help, but other posts say it doesn't.

Can anyone advise what my options are?

Thanks for any assistance.
Russell.
