Yes, the pattern is quite consistant.

Hrm, ldd says 'not a dynamic executable'. Not sure why that is.

I actually did test it with something printed immediately, but forgot to upload
that source when I sent the email just now (the currently uploaded source should have
the non-buffered io and the initial print. THe behavior is identical.

The behavior is also identical with LD_BIND_NOW set (perhaps related to the above
problem with ldd).

Ah, I mean the CORBA call Random_lrand48() returns a 0 instead of a
random number like it does when it executes correctly from the command
line and when it executes under gdb.
