to do if they cannot be found. - in try_dlopen, after find_handle() is called and returns 0 over and over, it was ignoring the return value of tryall_dlopen. As a result, sometimes the dlopen would fail and return 1 or more errors but nobody would notice. The handle would be returned as if the open had succeed, then any use of the handle would segfault because handle->loader was NULL. I have solved this problem by capturing the return value in errors, and then checking if errors>0 in the next if statement. - fix faulty boolean logic in lt_dlopenext that caused it to only search for libraries ending with .la. Now it says: if try_dlopen created a nonzero handle, return it. Otherwise, if there were any errors OTHER THAN file-not-found, return the NULL handle. If the only errors were file-not-found, continue to search. - just before loading the module in tryall_dlopen, do one final call to access() to check for existence of the file. Without this check, you sometimes get the "can't load module" error when in fact the problem is "file not found".
