Developers have encountered segfault of the REST test suite runner when playing the test suite with the additional tests of plugins not maintained inside the main repository (those tests are not at fault here).
The issue seems to be related to the usage of curl_multi_select() with different handles. At the moment I did not successfully isolated the issue in a minimal test case. The fact we are running the test suite in a CentOS 6 environnement with a version of libcurl "a bit old" probably does not help.
