Wow, that's deep trace, and that without any kind of recursion;-)
Never have ssen anything like that.

Something must be horribly broken with your system. Is that a
run-of-the-mill install or did you something "interesting" like
installing a new libc or mess around with the dynamic loader
(but then you probably wouldn't be able to start any programs
at all)? Does something similar also happen when you compile
other programs?

I have a feeling the problem is in the libraries, but don't know how
to go forward from this point.

There aren't going to be many libraries needed for this, actually
libc and ld-linux should be all and with them broken probably most
programs wouldn't work anymore. What do you get when you do

ldd a.out

wich tells you which libraries the program is linked against.
