I finally managed to reproduce it !
There was actually another important element: the problem occurs only 
when there is a stab warning in the a.out object file. I have been very 
unlucky, because I felt in that trap on my very first ELF test: I called 
the gets() function, which causes a linker warning in my libc because it 
is a dangerous function. Because of the bug the whole libc failed to link !

There is probably something wrong with N_WARNING...
