Quartus 17.1 SegFaults on Compilation Start - HELP?

[Altera_Forum]

Hi - so in order to upgrade to 17.1, I bought a new PC (my old one was running Centos 5), and I installed Centos 17.3 (current release). I downloaded and installed Quartus 17.1.  

 When I start compilation, it pauses for about 5 sec, and then it crashes with a Segfault (see below). It's not 100% consistent. The first time I tried loading some projects built in 17.0 it ran, once (re-run caused SegFault), and if I created a new project it SegFaulted 1/2 the time on the first run (and 100% on subsequent runs).  Sometimes I just get the message  Segmentation Fault quartus (core dumped).  Sometimes I get something like  kang2/jwinston67:  *** Fatal Error: Unhandled exception  0x8171: ERR_STACKWALKER::get_stack_trace(void const**, int, int, void*) + 0xb1 (ccl_err)  0xb015: err_terminator() + 0x4b (ccl_err)  0x63796: __cxxabiv1::__terminate(void (*)()) + 0x6 (stdc++.so.6)   0x63a36: __cxa_rethrow + 0x46 (stdc++.so.6)  0x1a5b64: QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) + 0x2f4 (QtCore.so.4)  0x1aa7c4: QCoreApplication::exec() + 0xb4 (QtCore.so.4)  0x1ea8: qgq_main(int, char const**) + 0x68 (quartus)  0x40720: msg_main_thread(void*) + 0x10 (ccl_msg)  0x602c: thr_final_wrapper + 0xc (ccl_thr)  0x407df: msg_thread_wrapper(void* (*)(void*), void*) + 0x62 (ccl_msg)  0xa559: mem_thread_wrapper(void* (*)(void*), void*) + 0x99 (ccl_mem)  0x8f92: err_thread_wrapper(void* (*)(void*), void*) + 0x27 (ccl_err)  0x63f2: thr_thread_wrapper + 0x15 (ccl_thr)  0x427e2: msg_exe_main(int, char const**, int (*)(int, char const**)) + 0xa3 (ccl_msg)  0x1f7a: main + 0x26 (quartus)  0x21c05: __libc_start_main + 0xf5 (c.so.6)  HELP??? /j

Try to remove completely and re-install version 17.1. You may have some luck.
