Tony, I386_DARWIN Juno is very prone to hang during startup going back at least until 2007/12/01.<br>But they certainly don't always hang.<br>I haven't found a version yet that doesn't hang. I'll look some more. I guess soon I should try other platforms?<br> Sometimes there is a pause and it continues. Perhaps the hangs I'm just being too impatient on??<br> But, then, it's a bit inconsistent.<br>Has it ever worked?<br>Race condition in Juno maybe?<br>It isn't always easy to build these old dates.<br>Caveats:<br> I'm using just current cm3cg. I started seeing as complain about older cm3cg output.<br> Current config files.<br> Build standalone (as current config files do with older compilers automatically, for "old" == missing the symlink functions).<br> Patched XSharedMem/IsSameHost to always be FALSE, though TRUE would be correct, FALSE seems safe, I have to read that code..<br><br>Here is 2007/12/01 hung.<br>It got as far as displaying "Curve" in the startup text that goes by.<br> <br>(gdb) thread apply all bt<br><br>Thread 9 (process 32852 thread 0x294f):<br>#0 0x96f432ce in semaphore_wait_signal_trap ()<br>#1 0x96f752c6

Tony both of these timestamps are somewhat prone to hanging during Juno I386_DARWIN startup. But they don't crash, er..well they do both fail assertions in text, but I just put current source in to address that.
