Hi,

This is apparently not the the current 3.7 (cvs) source for mapraster.c
since line 828 is in drawJPEG().  If you can update to the latest it would
be easier to help you fix the problem (or are you working on 3.6.3?).

The crash is occuring while reading from the TIFF strip buffer.  If you
are interested in tracing the problem, I would suggest printing out
xi, boffset, and the value returned by TIFFStripSize(tif).  Also, could
you provide a tiffinfo report on the tiff file?  Alternatively, point me
to the data, and minimal file demonstrating the problem?

Best regards,
