I suppose that it is a problem in your application in how it calls OpenSSL. The backtrace is not suspicious - if the crash is really on the access to s->s3->wbuf.left it would have to mean that it is somehow silently corrupted during the operation. Is your application multithreaded? As I don't see any other reports of regularly crashing applications which try SSL connects through OpenSSL I'd really need some simple reproducer to trace the crash more. First off all thanks for a quick response. I must confirm that, it's not a bug in openssl. I was not quite correct in my first report as the crash appears not during session establishment but renegotiation. Nevertheless your guess about multithreaded application has been right. I have debugged it a bit and have found that s->s3 was 'nulled' in one thread, so that in the other it caused segmentation. |
