Crash on Sql Select

[Erne]

Hello Ruslan,

I get this crash on SQLSelect but can't reproduce it reliably
sometimes happens and sometimes not in the very same conditions

I'll try to reproduce to make a Mantis entry, but meanwhile I send  
you this crash log that maybe can give you some clue of what's going on


Exception:  EXC_BAD_ACCESS (0x0001)
Codes:      KERN_INVALID_ADDRESS (0x0001) at 0xfffffffc
