Public bug reported:

This happens on one machine and not on another. It seems to be nothing
to do with the user's environment, since if I run "sudo guile-2.0
--version" I get the same problem.

strace shows:

strace guile --version

A successful run on another very similar machine shows a different
trace, with similar system calls being executed but in a different
order. I tried with 2.0.9 from Trusty and 2.0.11 from Vivid.

Title:
  "guile-2.0 --version" runs without output and 100% CPU forever

Status in guile-2.0 package in Ubuntu:
  New

Bug description:
  This happens on one machine and not on another. It seems to be nothing
  to do with the user's environment, since if I run "sudo guile-2.0
  --version" I get the same problem.

  strace shows:
