New issue 11 by timothy.ty.lee: lou_backTranslate() may leave some "outpos"
elements un-initialized
http://code.google.com/p/liblouis/issues/detail?id=11
To reproduce the problem:
1. Before calling lou_backTranslate(), fill outpos with -1's
2. Back-translate ",numb} #c = ,,y6" using en-us-g2.ctb
When you examine the values returned in outpos, it can be seen that some of
the -1 were not overwritten by the function. What should happen instead is
that outpos[0..inlen] should be set by lou_backTranslate().
This problem is present in the trunk, and affects all operating systems.
The attached patch aganist trunk overcomes the problem by filling outpos[]
with -1's to mark array as uninitialized when lou_backTranslate() starts.
Before returning to caller, the function examines outpos[] and fills in
unused elements in the array.
