Maybe this will help some guys
I got a new 32 bits laptop 3 months ago with Windows XP Sp3 (and a CD for Windows 7) and got that message when using strings udf functions (from freeudflIB OR FreeAdhocUDF) with Firebird 1.5.6 (either classic ou super)

I have found that updating Windows sp3 with lastests updates (about 103 Mbytes) solved this issue!
