Hallo,
LibreOffice v4.3.0.4 doesn't work on SSE1 CPUs anymore. Tested on AMD
AthlonXP (AMD K7) with Windows7 32Bit. Previous version was v4.1.0 that
worked properly.
Exception code is c000001d (illegal instruction). Probably thrown by
SSE2 instruction (or higher) that the K7 doesn't understand (it supports
"MMX, Extended 3DNow, SSE, PowerNow!").
This can usually be fixed by limiting the compiler (GCC) to SSE
instruction set.
Can you fix that?

Visual Studio 2012 has switched the default to "/arch:SSE2", if we want
to support those old CPUs we have to use "-arch:SSE" (or even
"-arch:IA32", although i'd hope every CPU that can run WinXP supports SSE).
that's reasonably easy to do for our own code, but probably a bit more
effort for the bundled external libraries...
The K7, which launched mid-1999, that is _before_ OpenOffice.org even
started, has been discontinued by AMD in 2005.. that is 5 years
_before_ libreoffice was launched, and 9 years before 4.3 was
released.
What compelling reason is there to run the lastest version of a
software on such old architecture ? and even more to the point, what
compelling reason is there to slow down everybody else for that.
