Hi,
even in zsh cvs from today I get the following strange behaviour:
ulimit -v $[200*1024]
ulimit -v
---> output 200
top
---> zsh crashes
This on a machines with more than 1Gb physical memory.
Thanks for any hints,

Hmm:
zsh% ulimit -v $[200*1024]; limit
cputime unlimited
filesize unlimited
datasize unlimited
stacksize 8MB
coredumpsize unlimited
memoryuse unlimited
maxproc 2040
descriptors 1024
memorylocked unlimited
addressspace 200kB <-- Note, not 200 megabytes!
(boom, zsh crashes)
On my machine zsh crashes instantly in tcgetattr() [a system library call]
while attempting to zwarn("fatal error: out of heap memory"). Just before
the ulimit call, `ps' shows `zsh -f' to be using 1900k+ of virtual memory,
so 200k is definitely not going to cut it.
Compare:
zsh% ulimit -s $[200*1024]; limit
cputime unlimited
filesize unlimited
datasize unlimited
stacksize 200MB <-- This one is correct
coredumpsize unlimited
memoryuse unlimited
maxproc 2040
descriptors 1024
memorylocked unlimited
addressspace unlimited
It looks like this has something to do with the convoluted #ifdef that
prevents duplicate case labels in rlimits.c when both RLIMIT_RSS and
RLIMIT_VMEM are defined, but I haven't yet figured out what to fix.
