[Bug 783622] Re: The Natty libfontconfig is crashing some Wine applications

[David Lerner]

The problem can also be fixed by downloading the Natty  i386 version of
libfontconfig1, extracting libfontconfig.so.1.4.4, moving it into
/usr/lib32, and running ldconfig. Adding libfontconfig.so.1.4.4 to the
ia32-libs package appears to be the appropriate fix.

Title:
  The Natty libfontconfig is crashing some Wine applications

Status in “fontconfig” package in Ubuntu:
  New

Bug description:
  Binary package hint: fontconfig

  Multiple Windows applications that used to work on Maverick are
  crashing on Natty. Stack traces show the crash happens in a function
  called from FcConfigSubstituteWithPat().

  Using LD_PRELOAD to load the Maverick version of libfontconfig instead
  of the Natty one fixes the problem.

  A verifiable test is to download and install http://www.justbasic.com/
  then try run it. It will crash with the Natty libfontconfig but work
  with the Maverick one.

  Note that this is the 32 bit library on x86_64, ie. its owning package
  is ia32-libs.

  An example stack trace:

  Unhandled exception: denormal float operand in 32-bit code (0x7e9d9310).
