Thanks. This might also explain an error I am trying to track down this
whole day :( On my main development machine I recently upgraded to glibc
2.3.1. When I got this email I checked on another machine that is still
running glibc 2.2.5 and all seems to work OK there...
I am also seeing strange things when using gij to interpret byte code on
the glibc 2.3.1 system:
