Title:
  Bogus FPE on underflow for exp(double)

Status in “eglibc” package in Ubuntu:
  New

Bug description:
  Glibc version 2.15 has a bug causing spurious FP crashes when calling
  exp(). It has been reported here:

  http://sourceware.org/bugzilla/show_bug.cgi?id=13705

  You can find all the details, including a testcase and the patch for
  libm in this report. I found that the 64-bit version of precise ships
  a version of glibc that still has this bug. I have not tested the
  32-bit version, but I assume it has the same problem.

  I am one of the developers of the open source code Cloudy and this bug
  renders our code completely non-functional. I would therefore like to
  urge you to ship this patch as an update for the precise distribution,
  especially since this is a LTS release.
