4.3.12 regression: fg'ing dead processes

4.3.12 regression: fg'ing dead processes

[Christian Neukirchen]

Expected:

emo ~%% zsh --version
zsh 4.3.11 (x86_64-pc-linux-gnu)
emo ~%% cat
^Z
zsh: suspended  cat
emo 20? 1& ~%% kill %1
emo 1& ~%% 
[1]  + terminated  cat
emo ~%% kill %1
kill: %1: no such job
emo 1? ~%% fg
fg: no current job

But on 4.3.12:

juno ~% zsh --version
zsh 4.3.12 (x86_64-unknown-linux-gnu)
juno ~% cat
^Z
zsh: suspended  cat
juno 20? 1& ~% kill %1
juno 1& ~% kill %1
kill: kill %1 failed: no such process
juno 1? 1& ~% fg
[1]  + continued  cat
^Z^Z^C^C
(terminal/shell completely hangs)

It seems the killed job didn't get removed from the list of backgrounded
processes or something?

Bart did some more work on this after 4.3.12, so I hope this is fixed in
the 4.3.12-test-2 release on ftp.zsh.org in pub/development.

Indeed, I'm not able to reproduce when using the current CVS:

torch% cat
^Z
zsh: suspended  cat
torch% kill %1
torch% 
[1]  + terminated  cat
torch% kill %1
kill: %1: no such job
torch% fg
fg: no current job
torch% print $ZSH_VERSION $ZSH_PATCHLEVEL
4.3.12-test-2 1.5486
torch% 

I haven't explicitly tried the test release from ftp.zsh.org but I have
no reason to believe any fix was applied after that.
