Applied, thanks. Note that it would be easier for us
if you could provide a context patch (this is, the output
of `patch -u <old_file> <new_file>'). The GNU patch program
is available for virtually all platforms, including
Windows.

The SubRule validation function processes the table incorrectly by not skipping over the context glyphs in the table.

the missing statement is
"p += ( ( Count1 -1 ) * 2 );"
after the limit checking of the SubRule Table in the "src/otvalid/otvcommn.c" file.
