Crash after process TLS about swift HOT 6 CLOSED

Hi admin,

I think these lines have problems, you free a pointer after create 'std::string'. So there is an error that double "free"

from swift.

Hi,

What are the steps to trigger this in Swift?
Can you please provide a full backtrace with locals of the crash.
Exactly which version of Swift is this on which platform?

from swift.

Hi,

I clone this repo: https://github.com/swift/swift.git

I build this repo in ubuntu 18.04

The Swiften crash with SIGSEGV, I can not get any backtrace although I try with GDB (or valgrind).

Thanks !

from swift.

Hi,

The line numbers in your paste don't seem to correspond to line number on either master or the 4.x branches, which is why I asked for the version. What are you doing in the client when it crashes? How would one reproduce this? Why does getting a backtrace not work?

from swift.

Hi,
I added some logging (SWIFT_LOG(debug)). So The line numbers in my paste don't seem to correspond to line number on either master or the 4.x branches. But I confirm that i clone from this repo: https://github.com/swift/swift.git

It extracts to crash in this line context_ = createSSL_CTX(mode_);:

sslCtx = std::unique_ptr<struct ssl_ctx_st> = {get() = 0x0}

My openssl library: OpenSSL 1.1.1c 28 May 2019

-L/usr/local/lib -lssl -lcrypto
-I/usr/local/include

Thanks !

from swift.

Hi admin,

I try with a single test => OpenSSL works fine.

But when I add Swiften to our project, It is always to crashing at this line:
sslCtx = std::unique_ptr<struct ssl_ctx_st> = {get() = 0x0}

I think Swiften library there are some issues when connect to XMPP servers (thought proxy such as: nginx ..v.v.)

Thanks !
