Title:
  sprof fails to work with shared objects

Status in “eglibc” package in Ubuntu:
  Confirmed
Status in “eglibc” package in Debian:
  Unknown
Status in “eglibc” package in Fedora:
  Unknown

Bug description:
  Binary package hint: libc-dev-bin

  When I try to profile a compiled shared object, sprof always fails
  with: "Inconsistency detected by ld.so: dl-open.c: 672: _dl_open:
  Assertion `_dl_debug_initialize (0, args.nsid)->r_state ==
  RT_CONSISTENT' failed!"

  I have the environment variables LD_PROFILE and LD_PROFILE_OUTPUT set
  up as you would expect and a file.so.profile file is created along
  with gmon.out.

  Both the main program and .SO are compiled and linked with -pg
