>Description:
Randomly, but regularily the XServer crashes ever since I upgraded to
XFree 4.2.
>How-To-Repeat:
The XServer receives a floating point exception in the driver function
called from:
#3 0x814244d in miPolySegment (pDraw=0x8a6a000, pGC=0x8a62400, nseg=3,
pSegs=0x8b3e3a0) at mipolyseg.c:78
#4 0x81679d5 in miSpritePolySegment (pDrawable=0x8a6a000, pGC=0x8a62400,
nseg=3, pSegs=0x8b3e3a0) at misprite.c:1406
#5 0x80b25b7 in ProcPolySegment (client=0x8a62100) at dispatch.c:1882
#6 0x80afdf5 in Dispatch () at dispatch.c:462
#7 0x80bfd6d in main (argc=5, argv=0xbfbfdcdc, envp=0xbfbfdcf4) at main.c:454
#8 0x806bbb0 in ___start ()
it then dies with a SIGTRAP and dumps core. For whatever reason I did not get
symbolic information for the calls beyound the function pointer.
>Fix:
n/a yet, will investigate further

>Unformatted:
i386, running -current, latest xsrc, XFree 4.2
