I tried compiling electricfence from pkgsrc (because I want to track down a
SIGBUS in tripwire), but one of the tests invokes mmap with a
negative len:

24772 tstheap  CALL  mmap(0x405ce000,0xffffffffb3494000,0x3,0x1002,0xffffffffffffffff,0,0)
24772 tstheap  RET   mmap -1 errno 22 Invalid argument

To make things even worse, gdb doesn't really work because
it can't even do a simple "bt" in main.c. If somebody could
comment on that as well even better :-)  The stackframe is
almost always trashed.

Does that mean that I should look somewhere else, e.g. in libc
or a broken gcc? I'm currently compiling a new world which might
take a couple of hours. If I'm not mistkaen the kernel should be
- more or less - not responsible for this borkedness.

FWIW, uname says:
NetBSD menelaos 1.5Y NetBSD 1.5Y (MENELAOS) #0: Mon Nov  5 14:15:41 CET 2001\
     stolz@menelaos:/usr/src/sys/arch/sparc64/compile/MENELAOS sparc64
