zsh-4.0.7 memory fault in IRIX 6.5

[Joachim Backes <backes@xxxxxxxxxxxxxx>]

Hi,

having problems with zsh-4.0.7 (and earlier) on IRIX-6.5:

if I have an (very old) /etc/zshenv with the contents

        setopt shwordsplit

then zsh dies directly after start with "memory fault". The reason
seems to be the (invalid ??) contents of /etc/zshenv.

I made a system trace of zsh and got the following (the first lines
are omitted) result:

...


   18mS[  3]                 : ioctl(10, TIOCGSID, 0x7ffb7de0) OK
   18mS[  3]                 : getsid(0) = 8340897

   19mS[  3]                 : stat("/etc/zshenv.zwc", 0x7ffb7c50) errno = 2 (No such file or directory)
   19mS[  3]                 : stat("/etc/zshenv", 0x7ffb7ce8) OK
   19mS[  3]                 : open("/etc/zshenv", O_RDONLY|O_NOCTTY, 0) = 3
   19mS[  3]                 : fcntl(3, F_DUPFD, 10) = 11
   19mS[  3]                 : close(3) OK
   19mS[  3]                 : fstat(11, 0x7ffb7d10) OK
   19mS[  3]                 : sigaction(SIGINT, {flags=0 handler=0x1006b0d0 mask=[<none>]}, 0) OK
   19mS[  3]                 : fstat(11, 0x7ffb6b10) OK
   19mS[  3]                 : ioctl(11, __OLD_TCGETA, 0x7ffb6ac0) errno = 25 (Inappropriate I/O control opera
tion)
   19mS[  3]                 : read(11, "setopt shwordsplit\n", 4096) = 19
   20mS[  3]                 : sigprocmask(SIG_BLOCK, [SIGCLD], [<none>]) OK
   20mS[  3]                 : received signal SIGSEGV

An empty /etc/zshenv makes no trouble.
