Hi All,

I'm testing Jake's fragment 7 csd and get a crash:

http://csound.noisepages.com/2010/02/fragments-of-a-bohlen-pierce-composition-pt-7/

gdb says it's because:

Program received signal SIGSEGV, Segmentation fault.
0x6f210efd in chnclear_opcode_perf (csound=0x4c0048, p=0x4dee1c)
    at OOps\bus.c:972
972         csoundSpinLock(lock);
(gdb) bt
#0  0x6f210efd in chnclear_opcode_perf (csound=0x4c0048, p=0x4dee1c)
    at OOps\bus.c:972
#1  0x6f269566 in kperf (csound=0x4c0048) at Top\csound.c:1360
#2  0x6f269856 in csoundPerform (csound=0x4c0048) at Top\csound.c:1457
#3  0x00401687 in main (argc=2, argv=0x3e2598)
    at frontends\csound\csound_main.c:136

Sure enough, chnclear is trying to use a lock that it hasn't
pre-acquired in it's init method.  I've checked in a fix to acquire a
lock and it seems to fix things up.  Could someone else test? My guess
though is that it might be a platform dependent bug as this code
doesn't seem to have changed in a while.

Thanks!
steven

No crashes here on OSX. This is CVS from the weekend, which I am going  
to release as a bugfix package (all reported bugs seem to be fixed).

With your latest opcodes added? We haven't heard from Michael in a
while, is he still looking after the windows installers? There still
isn't a 5.12 available for windows. Not a bad thing I guess in light
of recent bugs.

I am still responsible for the Windows installers.

However, as I mentioned a month or so ago, my apartment is being
renovated and I do not have full-time access to my Windows computer,
therefore I am not maintaining the installers until I have moved back
into my apartment. That looks to be sometime in late March or early
April now.

On the plus side, I have been able to finish coding and booking in
samplewise access to spin, spout, and numbered busses. These should
now show up in the API wrappers if you do a complete clean and
rebuild. Not tested yet.

I also fixed a serious, long-standing bug in MIDI import into the
CsoundAC.Score class, if anyone else is using it. This should now
provide an adequate means of reading external MIDI files into Csound,
with the plus that they can be extensively fiddled with using CsoundAC
once imported.

Regards,
Mike

Hi,
I tried fragment7.csd w/Bohlen Pierce scale on Mac with 5.11, and ran fine.
Then tried on linux, f12, with 5.12 beta and get segfault.
regards,
Jim Hearon

Hi,

It's working fine on 5.12.2 on OS X Snow leopard. I think this was
specifically fixed for 5.12.2

Cheers,
Andrés

I think it may have been a threading-implementation specific issue, as
it worked on OSX in previous versions.  My guess is OSX locks are just
implemented differently.

Oh, you're right, sorry, it was a different bug which was fixed...
