I see a similar bug with both gcc 4.6.0 and 4.6.1. In the library crypto++ (v.
5.6.1, http://www.cryptopp.com/), the algorithm Salsa20 produces wrong outputs
when compiling with -O, -O2, -O3, but the bug dissapears as soon as -fno-inline
is added. The output is always correct with gcc 4.5.x. These results were
obtained on a 64-bit linux platform (ubuntu 11.04). 

I cannot post the source code that produces the errors; I do not have a reduced
test case.
