Hello, We tried to investigate more about the problem today.
>From what we understood from the ssl.exe test code: The test throws an exception on the on_transport_error() because the certificate is wrong. This triggers the destruction of the objects on the stack. Apparently, there is a memory corruption in iocpdesc_t structure: We are calling (selector)->triggered_list_tail->triggered_list_next while (selector)->triggered_list_tail is null [in triggered_list_add() in selector.c line 300]. Therefore we have the crash. Can you help us find more info about the bug? The crash is very low level and we have not very much experience in the proton-c layer... Thank you, Regards, Antoine -----Original Message----- From: Adel Boutros [mailto:adelbout...@live.com] Sent: lundi 17 octobre 2016 19:30 To: users@qpid.apache.org Subject: [Proton-c 0.14.0][Visual Studio 2013] Failing ssl unit test only in Debug mode Hello, We are compiling Proton-c 0.14.0 and its C++ bindings in 2 modes: RelWithDebInfo and Debug. For the RelWithDebInfo mode, all tests are green. For the Debug mode, we have a ssl test failing. We are using OpenSSL 1.0.2h. Swing and Cyrus are disabled (not found). Can you please help us find the issue?
