-Problem
--------
-
-Decoding the file frle_bug.tif causes a crash (such as with tiff2rgba). 
-
-In particular the array dsp->runs allocated in Fax3SetupState() is overrun 
-by 4-8 bytes.  This occurs when Fax3DecodeRLE() processes the first
-scanline.  The EXPAND1D() macro advances "pa" to be thisrun+512 (an
-alias for dsp->runs), pointing just beyond the end of the array.  Then 
-the call to _TIFFFax3fillruns() does an "*erun++ = 0;" which writes beyond 
-the end of the array.
-
-In the short term I have modified the dsp->runs allocation to add eight
-extra bytes to the runs buffer; however, I am only doing this because I
-don't understand the algorithm well enough to change it without risking
-more adverse side effects.
