The problem may be due to not using thread safe programming methods. Not all libraries are thread safe. For example, libraries (such as GTK+) are not set to thread safe mode by default and must be initialized as thread safe.

On the other hand - Segmentation faults are usually caused by attempting to write to memory that shouldn't be written to (i.e. a buffer overflow) so make sure you are not accidently freeing memory in one thread while attempting to write to that same memory via another thread.

curl_global_cleanup

curl_global_cleanup(3)						  libcurl Manual					    curl_global_cleanup(3)

NAME

       curl_global_cleanup - global libcurl cleanup

SYNOPSIS

       #include <curl/curl.h>

       void curl_global_cleanup(void);

DESCRIPTION

       This function releases resources acquired by curl_global_init(3).

       You should call curl_global_cleanup(3) once for each call you make to curl_global_init(3), after you are done using libcurl.

       This function is not thread safe. You must not call it when any other thread in the program (i.e. a thread sharing the same memory) is run-
       ning.  This doesn't just mean no other thread that is using libcurl.  Because curl_global_cleanup(3) calls  functions  of  other  libraries
       that are similarly thread unsafe, it could conflict with any other thread that uses these other libraries.

       See the description in libcurl(3) of global environment requirements for details of how to use this function.

       curl_global_init(3), libcurl(3),
