The result is undefined:

1. Stroustrup:
http://www.research.att.com/~bs/bs_faq2.html#evaluation-order

2. C FAQ section 3.2:
http://www.faqs.org/faqs/C-faq/faq/

The same problem is with this line of code:

t = ((m_inputBuffer[i++] << 4) & 0x30) | (m_inputBuffer[i] >> 4);

Many people downloaded XSEC C++ library and used it, but haven't ever
run into problems with Base64 encoding. I had problems with Base64
encoding when I started to play with static linking. Then, my VC6
started to behave (to compile the code) differently then before.

Best regards,
Milan
