Hi,

  I met the same bug on redhat 6.0 of x86_64. I use dlopen with -RTLD_DEEPBIND
flag in my program, but it will crash once I start my program. But the this
program runs well on SLES.

  And if I compiled using '-g' or '-O0', then it won't crash.
  Could someone help to look at this? It stops our product running on
RH6/x86_64
