Thanks for the reply, I can not reproduce the problem with a small
sample application. The same code works there but does not work in the
complex application (there might be differences in the project
settings that I've missed). When I use the same call to the FileSource
constructor from both projects, they differ in the way
while (size && m_stream->good())
evaluates. In the short test application m_stream->good() returns
false in the second iteration of the loop, letting the method
correctly return, in my application context this method always returns
true on the same file (while 0 bytes are read from the stream
afterwards, leading to my problem).
Also, I do not really suspect this to ba problem of CryptoPP rather
something in the overall compiler settings, or an include. I was just
hoping someone might have seen this behavior before and recognizes my
mistake.
Thanks for your help
Tom
