Severity: normal
Dear Maintainer,
I am trying to run a program detached in the background from an ssh login,
like
nohup <prog> <arg>
where <prog> is my executable and <arg> a configuration file.
The combination <prog> <arg> runs without issue. As far as I understand from
the documentation (man or info respectively, <arg> denotes program
(as opposed to nohup) arguments. Now, when prefixed with nohup, nohup segfaults
within about a second, apparently (strace) due to an access to
an invalid file descriptor (see strace excerpt below) - I had expected
nohup.out to be
created and contain the program output (possibly with the exception of stderr).
