You mean it is NULL or some huge illegal value? I don't see how
that can happen. The get*_thread() functions doesn't modify that
string at all. Unless someone else stepping on 'conn->async'.
Do you have an example program I could try?

That shouldn't happen; USE_THREAD_GET* isn't defined unless you defined
it outside setup.h youself. Looks like your debugger isn't giving you the true
story or the bug is elsewhere.
Try to build libcurl with -DCURLDEBUG and watch for allocation errors.
Look at src/main.c and curl_memdebug("memdump") for how that's done.
