Description of problem:
I'm trying to 

Version-Release number of selected component (if applicable):


How reproducible:
100% in F13 virtual machine hosted on F11 host.

Steps to Reproduce:
1. compile the attached program with make test CFLAGS='-g -O2' LDFLAGS='-lcrypto -g'
2. set breakpoint to main()
3. use next command to step over the FIPS_mode_set call
  
Actual results:

gdb prints:
(gdb) n
[Thread debugging using libthread_db enabled]
Cannot find new threads: generic error


Expected results:
to be able to continue debugging


Additional info:
You need to have undone prelink on libcrypto and libssl libraries. These libraries are dlopened during the FIPS_mode_set() call. The libcrypto is also DT_NEEDED so it does not cause anything during the dlopen() but when the libssl is dlopened it will break the debugging.
