#51911: libepoxy: crash in gtk_init_check when calling epoxy_glx_version -----------------------+---------------------- Reporter: manus@… | Owner: devans@… Type: defect | Status: assigned Priority: Normal | Milestone: Component: ports | Version: 2.3.4 Resolution: | Keywords: Port: libepoxy | -----------------------+---------------------- Comment (by manus@…): Found the issue, in https://github.com/anholt/libepoxy/blob/master/src/dispatch_glx.c#L104 the call to glXQueryExtensionsString returns NULL and not an empty string. The call in `epoxy_extension_in_string` does not check for that. So checking that the `extension_list` is null would simply fix the issue: https://github.com/anholt/libepoxy/blob/master/src/dispatch_common.c#L350 -- Ticket URL: <https://trac.macports.org/ticket/51911#comment:7> MacPorts <https://www.macports.org/> Ports system for OS X
