IMO the problem is not fork, you can't do anything useful to create
subprocess without fork on *NIX systems.
fork is allowed to execute in multi-thread environment.

Hmm so how would you write this?

Which socket file?
(In practice ‘exec-command’ would only fail if the program cannot be
found.)

The socket created by 'open-server-socket', used by 'herd stop' and the
like.

Hi,
I'm digging on old compiler versions for bootstrapping purposes and I realized
that gcc 4.7 and 4.8 packages don't compile on x64.
We have been able to reproduce the failure of gcc 4.7 but we didn't test the
4.8 error that far.
In gcc-4.7 the error is the following:
./md-unwind-support.h:

I noticed that some Guix packages depend on LibreSSL, but it seems that
we are not successfully keeping this package up to date with upstream
security releases:
https://www.libressl.org/releases.html
Will anyone step up to maintain this package? Or should we remove it
from Guix?
Hi Ekaitz
Not that I am in any position to answer the question, but could you
share a little bit more context?
Did the error occur when you were compiling gcc-4.7 or do programs
compiled with this compiler have this issue?
What path led you to gcc-4.7? Can you share your compilation setting

More specifically I mean the output of that command is:
