curl_slist_append() is a public libcurl function that has worked the 
same way for many years and that's also unmodified since a long time.


It seems likely that this crash is caused by your application's use of 
this function.


If you think differently, then please provide a stand-alone example 
source code for a program that shows this problem reproduced. 



Also please review libcurl thread safety. [1]

 8. We are suspecting that this might be an issue with the new libcurl
 version.


This function is frequently used by applications and even internally by 
libcurl itself and yet nobody else has reported a problem with this function 
and all our own tests and CI show it working just fine.
