This message comes from dynamic loader when debugging is turned on.
You can see this for yourself doing:

  env LD_DEBUG=symbols /bin/date

The fact that you are getting these messages without LD_DEBUG means
that you have a bug in your program, which corrupts dynamic loader
into believing that debugging is turned on.

The bug likely exists in 32-bit version as well, but you corrupt
something else, and so do not observe the result of corruption.

You may wish to test your program with Valgrind, Purify or Insure++
and fix all bugs that they report.
