Topic: Crash when calling wolfSSL_CTX_load_verify_buffer() since v2.6.2
Hello,
Since wolfSSL embedded SSL v2.6.2, my program crashes in wolfSSL_CTX_load_verify_buffer(), which I use to load a CA cert. It's fine in v2.6.0.
I've also tested with the latest development code.
OS: Windows 8 x64
Compiler: VC++ 2012 (XP target)
