> the preprocessed source of Salsa20 from Crypto++, with gcc 4.6.0, option -O2
I just discovered that the bug is present only when crypto++ is compiled with
NDEBUG defined, which is not the case in the preprocessed files above. I will
re-post updated files (output of the whole compilation of test case with
-save-temps).
