Re: autoconf stalls while checking "atomic builtins for 64 bit data types"

Hi there,

while trying to rebuild a few packages on my fairly old hppa box (PA8600
CPU) I noticed some of them like rsyslog and syslog-ng stall during
configure, with a conftest program eating 100% CPU. Funnily, killing
that process does not abort the build and produces a usable package.

The sync operations for double word operations were introduced in gcc on 2014-11-21. These require kernel support.  I suspect the stalls occur because your kernel is too old and doesn't support double-word atomics.  Possibly, installing the current Debian kernel from
unstable would resolve the problem.

Helge can provide an account on phantom for development if necessary.
