If you use the getinmemory.c example *verbatim*, then you should
not see crashes related to the write callback.

"Handl[ing] multiple http-calls at the same time (via detached
threads)" is a generic description, so it's hard to tell if you
are breaking any libcurl thread rules.

Perhaps you could share your updated write callback mechanism code
and how you manage your multi-threaded libcurl application?
