There, it came back.

I think to summarise, the problem is:

  - When strlen(argv[0]) <= 6, it works fine.

  - When strlen(argv[0]) > 6:
     -  If the executable is dynamicaly linked, runs as if it were ld.so.
     -  If static, segfaults (SIGILL if you run in ktrace).

Test example:

rmh at orthanc:/tmp$ ./test
argc = 1
argv[0] = ./test
rmh at orthanc:/tmp$ /tmp/test
Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...]
You have invoked `ld.so', the helper program for shared library executables.
[...]

I suspect it has something to do with missing changes that freebsd didn't push
into upstream binutils.
