       Hi Max,

       I can't answer your question directly, but just wondering why

you are

       using
       the itimer VM when the are known issues with external calls, and

not

       the
       heartbeat VM?

   Because of the root user issue, and also because I don't care about

that

   much at the moment. I'm still experimenting and for those

experiments it

   doesn't matter which VM I use. Thirdly, the itimer VM is the one I

get when

   I use 'curl get.pharo.org/60+vmLatest | bash', which is convenient

to get

   the latest VM, and to minimise differences between the VM's we built

the

   same one. I will definitely consider using the threaded VM for

production.

       P.S. I would love to see OSProcess working in 32 bit mode.

   Well, it does work already, just not when we build the VM ourselves

:/

Interesting, I had the impression that for Pharo 6 OSProcess didn't work

in

32bits, only 64, but I'm also building my own VM.  I'm away from my PC,

but

I'll try and take a look.

I'm seeing the same behaviour as you, i.e. OSProcess works in a VM
downloaded from get.pharo.org, but locks up when using the VM I
compiled.

Have you looked at the build logs and eliminated compiler version, command
line flags, etc?  One important file is the config.h that is produced in
the build directory.  It might be informative to compare the one configure
is producing on your systems and the one that the binary builds creates.

Both VMs (threaded heartbeat) are based on the same source code, i.e.:

VM: 201705022326 https://github.com/OpenSmalltalk/opensmalltalk-vm.git $
Date: Tue May 2 16:26:41 2017 -0700 $

I'll try and take a look at this eventually, but I'm not sure how long
that will be (several weeks away, at least).

If you figure it out, please let me know.

Thanks!
Alistair
