9.1+sp2 10.0 Quartus hangs 100% complete - (solved)

[Altera_Forum]

The quartus tools parse /etc/issue (and /etc/redhat-release and a couple of others) after executing the code but before writing the log file out. 

 If the file exists but is empty (in my case it contained two line feeds, '\n\n'), the tool hangs.   Snippet from strace: === uname({sys="Linux", node="sys7000-2", ...}) = 0 access("/etc/SuSE-release", F_OK) = -1 ENOENT (No such file or directory) access("/etc/fedora-release", F_OK) = -1 ENOENT (No such file or directory) access("/etc/redhat-release", F_OK) = 0 open("/etc/issue", O_RDONLY) = 9 fstat(9, {st_mode=S_IFREG|0644, st_size=2, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2aaaab9f0000 read(9, "\n\n", 4096) = 2 read(9, "", 4096) = 0 === Demonstrated on Quartus 9.1 sp2 and Quartus 10.0

Sorry not quite right 100% cpu usage not progress... 

 About 9% in, it prints a red "error: entity $x instantiated but not analysed"`. And it appears to hang here, at 100% cpu usage. I would expect it to stop but it doesn't
