Ah, it gets environ just fine, but not __environ, which getenv uses.
Not sure what's happening, but it looks like some relocation quirk.
I'll look again.

Breakpoint 1, call_init (l=0x7ffff7ff9198, argc=1, argv=0x7fffffffdbd8, env=0x7fffffffdbe8) at dl-init.c:35
35      {
(gdb) p __environ
$3 = (char **) 0x0
(gdb) p environ
$4 = (char **) 0x7fffffffdbe8
(gdb) p __environ
$5 = (char **) 0x7fffffffdbe8

Thanks,
Siddhesh
