Comment (by chust):

 Replying to [comment:3 felix]:
 > Thomas, can you give any hint on how to debug this?

 In the procedure call to sqlite3:map-row the only tasks TinyCLOS has to
 perform are resolving some generics to the correct methods (specifically
 sqlite3:map-row, sqlite3:bind!) and extracting the native structure
 pointer from the <sqlite3:statement> object.

 As I cannot reproduce any segfault inside sqlite3:map-row on my machine I
 don't know what goes wrong here :-(

 Just guessing into the blue: If this only happens on 64bit architectures,
 maybe the pointer extraction from the wrapper object garbles the upper
 32bits of the pointer word somehow?
