>Description:

Compiling any program with something like:

	c++ -m32 -pg -g -o hello test.cpp

creates a binary that crashes early in startup:
  0x000499c4 in dl_iterate_phdr ()
  0x00017d74 in __libc_static_tls_setup ()
  0x0004f11c in _libc_init ()

because auxinfo is not set and _dlauxinfo() returns a NULL pointer.

>How-To-Repeat:
s/a

>Fix:
n/a
