Under NT, it just throws an exception. Probably is exploitable if you dinked with it enough. Instruction well in the executable's range references memory at 0x1.MS-DOS gzip screws-up totally.
With your altered.gz
MD5 (altered.gz) = bd5fc9d6973a308f13dfe5de54d28e02
HPUX 68k => loops forever
HPUX B.10.20 => loops forever
SunOS 4.1.x => segmentation fault
Solaris 2.x => segmentation fault
Solaris x86 2.x => segmentation fault
MkLinux 2.0.30-osfmach3 PPC => segmentation fault
Linux 2.0.30 #2 i586 => segmentation fault
MacOS 8.0 68k => loops forever
MacOS 8.0 PPC => invalid compressed data--format violated
(I'd be even hapier if I knew why it doesn't crash...)
