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:
[EMAIL PROTECTED]:/tmp$ ./test
argc = 1
argv[0] = ./test
[EMAIL PROTECTED]:/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.
