Michal, does the bug not happen if you compile ksh with out
optimisation, i.e. -g and not -O*?

Michal, does the bug not happen if you replace echo $(latestver) with
echo ${ latestver; }?
${[blank]cmd;} is like $(cmd) but does not create a sub shell for the
command substitution. Might be a related issue, based on Roland's
experience.

Hi,
I found regression in ksh. One my script hang and ksh started to eat memory
very quickly. This happens with ksh 2012-01-01 and newer, ksh 2011-06-30
works fine. I found it only now, because the script causing this is the
script that updates ksh package to newer version.
This is simplified reproducer:
#!/bin/ksh
latestver()
{
rpmdev-vercmp 20120214 20120229>/dev/null
}
echo $(latestver)
but it depends on rpmdev-vercmp, so I don't know how much useful it is for
you.
When I remove /dev/null redirection or when I call latestver directly, it
works fine.
Attached are two strace outputs. kshbroken.log was obtained with 2012-02-29,
kshworking.log was obtained with 2011-06-30.
