Description martin.dieringer 2014-08-11 15:29:14 UTC
I have to say USE_GCC=yes for vdr, otherwise it crashes right on startup
Comment 1 John Marino freebsd_committer 2014-08-11 15:50:08 UTC
over to maintainer
Comment 2 Juergen Lock freebsd_committer 2014-08-11 17:55:34 UTC
Do you actually need USE_GCC=yes, or is USE_GCC=any sufficient?

(vdr doesn't crash here, neither on 9.2 nor on 10.0 and the backtrace in private email didn't tell me the actual cause - so I guess we'll just have to add an USE_GCC that works for you for now.)
Comment 3 martin.dieringer 2014-08-12 14:26:43 UTC
USE_GCC=any compiles with g++47, too, so for me it is sufficient

Committed.  Thanks!
Comment 6 Tijl Coosemans freebsd_committer 2014-08-12 16:13:30 UTC
What architecture is this (output of "uname -m")?
Comment 7 martin.dieringer 2014-08-12 16:16:34 UTC
FreeBSD 10.0-RELEASE-p3 #0: Tue May 13 18:26:10 UTC 2014     root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  i386
Comment 8 Juergen Lock freebsd_committer 2014-08-12 16:19:04 UTC
You may be onto something...  It didn't crash with clang on 10.0-R/amd64 .
Comment 9 martin.dieringer 2014-08-12 16:23:53 UTC
Doesn't crash on my amd64 machine either AFAIR.
Probably the USE_GCC could be conditional ...

  - Turns out the 10.0-R clang crashes I couldn't reproduce (on amd64) were
    in fact on i386 - since this was the first report I got of this kind
    (and I don't have an i386 box anymore myself) let's assume it's an
    i386 issue.  So change the USE_GCC=any to be i386-only.

Comment 11 Tijl Coosemans freebsd_committer 2014-08-12 17:02:44 UTC
You should take a look at multimedia/gstreamer1-libav/Makefile.  It adds "-mstack-alignment=16 -mstackrealign" to CFLAGS for clang && i386.  This realigns the stack on a 16 byte boundary when calling a function.  Some asm code that uses SSE instructions relies on that.

Created attachment 145727 [details]
clang/i386 stack alignment patch for testing

Can you test this patch if it also fixes the crashes?  And if it does rebuild all your plugins since they (may) inherit these changed C{,XX}FLAGS and then see if everything still runs?

Comment 13 martin.dieringer 2014-08-12 18:58:16 UTC
Unfortunately not. PORTREVISION 6 is ok, 7 crashes.

I recompiled all plugins too (with clang...)
Comment 14 Juergen Lock freebsd_committer 2014-08-12 19:18:43 UTC
Ok then I fear the USE_GCC will have to stay for i386.

Thanx for testing!
