This looks like a toolchain problem somehow:
173 ktrace RET ktrace 0
173 ktrace CALL execve(0xbfbffd6f,0xbfbffcb0,0xbfbffcb8)
173 ktrace NAMI "./a"
173 a RET execve 0
173 a CALL readlink(0x804a6d4,0xbfbffbb4,0x3f)
173 a NAMI "/etc/malloc.conf"
173 a RET readlink -1 errno 2 No such file or directory
173 a CALL mmap(0,0x1000,0x3,0x1002,0xffffffff,0,0,0)
173 a RET mmap 536870912/0x20000000
173 a CALL break(0x804c000)
173 a RET break -1 errno 12 Cannot allocate memory

I thought programs started out at 0x0 or at least close to zero ?
