ksh93: Exec format error

[Martin, Galen]

Greg,

I just read your entry on a  freebsd forums about ksh93: Exec format error.  We just upgraded some machines to Solaris 5.11 with the same version of ksh93 and are experiencing the same issue.
I have been searching for a resolution to this problem with no success.  Did you ever find a solution to this problem?

Here it is to refresh your memory.

I've been encountering the same error for some time now, but never got
around to reporting it.

Here's a fairly reliable way to repeat:

host -t a google.com. | awk '{print $NF}' | while read IP
> do

> done
host: host: cannot execute [Exec format error]
host: host: cannot execute [Exec format error]
host: host: cannot execute [Exec format error]

199.227.125.74.in-addr.arpa domain name pointer dfw06s33-in-f7.1e100.net.

It looks like some sort of race, because it's pretty random whether the 
error occurs or the command executes.

$ pkg info -o ksh93

$ echo $KSH_VERSION
