Hi,

I am trying to to lib curl to work with the Security framework on iOS and have a simple application where I am testing easy / multi HTTP secure connections. I have a lib curl configuration that I can run on my main thread or on a separate thread I have created (like an HTTP service thread). I have two versions, one based on curl_easy, another on curl_multi API. lib curl runs successfully if the code is on the main thread, but it will crash deep inside iOS framework if it runs on the http service thread (_retainedComponentString)

The stack trace is below :

* thread #6: tid = 0x2337, 0x34060e0a CoreFoundation`_retainedComponentString + 14, stop reason = EXC_BAD_ACCESS (code=2, address=0x2fe94d10)

    frame #20: 0x0031c364 Gladiator`curl_easy_perform + 260

The behaviour is the same whether I use easy or multi API.

Could the problem be related to how I have built libcurl?
I am using 7.32.0 and building against SDK 6.1 using :
--disable-shared --with-darwinssl --without-libssh2 --without-ca-bundle --without-ldap --disable-ldap --disable-ftp --enable-debug

Any suggestions?

Thanks
Arcin
