Bug#203722: How to handle the -mieee SIGFPE problem in normal Debian packages



Hi,

Please respect the Mail-Followup-To, as I'm not subscribed to this
list, and the discussion is relevant to #203722.

I'm currently looking at the following bug report
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=203722
about a frequent SIGFPE on an alpha machine.  I guess we all know the
cause of this bug, namely the non-standard alpha FPU semantics.

My question is about how to handle this bug:
IIUC, there are the following options:

1 Fix upstream FP calculations to not trigger SIGFPEs. this is
  unfortunately not an option imho, because of lack of interest of
  developers.
2 make all KDE programs install a SIG_IGN SIGFPE handler.  This can be
  done in kdelibs, and would be little work.
3 make upstream configure detect alpha and compile with -mieee if so.
4 wait for the gcc alpha patch to be included into gcc, which was
  posted on this list recently.

What option would you suggest the Debian KDE packages take ?  I don't
think there is any very FP-intensive code in the KDE packages, so
performance is not really that much of an issue.

cheers
