https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D242266 Dimitry Andric <dim@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dim@FreeBSD.org --- Comment #3 from Dimitry Andric <dim@FreeBSD.org> --- It looks like you are tickling some old bug in 6.0.1 which makes it use way= too much memory for this particular compile command. I tried on 12.0-RELEASE a= md64 with a lot of RAM, and I got the following time(1) output: 84.83 real 31.36 user 53.31 sys 6560428 maximum resident set size 40472 average shared memory size 2587 average unshared data size 255 average unshared stack size 3201539 page reclaims 1370 page faults 0 swaps 1379 block input operations 5 block output operations 0 messages sent 0 messages received 0 signals received 1383 voluntary context switches 1152 involuntary context switches E.g, it needs 6.3 GiB of memory and more than a minute to compile. This is obviously never going to work on i386, which can use up to 4 GiB of memory = for user processes. Compare this to clang 8.0.1 on recent stable/12: 23.17 real 18.12 user 3.36 sys 314944 maximum resident set size 42981 average shared memory size 358 average unshared data size 253 average unshared stack size 69152 page reclaims 1090 page faults 0 swaps 1100 block input operations 5 block output operations 3 messages sent 0 messages received 0 signals received 1105 voluntary context switches 346 involuntary context switches That needs only ~308 MiB of memory, and a little more than 20 seconds. I'm unsure what will help here. You could try leaving out the -march=3Dnati= ve stuff, or lowering the optimization level. The former should be easy enoug= h, but for the latter, I don't know how to achieve that with the port. Another alternative is to do a binary upgrade to 12.1-R, and work from ther= e. --=20 You are receiving this mail because: You are the assignee for the bug.=
