Okay, rebuilt Ardour against the new zlibs (not sure if it matters, but figured it couldn't hurt). Still getting segfaults. It's not as often, but it's still more often than not. As for other problems, I just discovered that Krunner is freezing up. I'm not sure it's related, but it wasn't happening before. I'm off to see if it's happening in anybody else's user account.
Okay, I think the problem is licked. I've still got one session that wants to segfault, but I think I know why. I'll try to use it a bit as the day wears on and report back. Now if I could just get the firewire working...
Has anyone tested zlib on x86 yet? I wasn't 100% sure when I wrote that patch whether the fix should be applied to both internal and external handling, or what the effects might be on 32-bit systems. The zlib.h is quite different compared with the previous version... honestly, I'm not even certain I have correct logic in there, but the idea is to use the gz*64 functions whenever _FILE_OFFSET_BITS == 64. The invert done in Gentoo's patch would also work, but I think it also causes the replacements to occur in cases where it isn't needed (which should only be an issue if the system did not support large file handling at all, but still).
if can be useful, I have a netbook with slackware-current.
- I updated it to the zlib in testing;
- I rebuilt the zlib package (without reinstalling) running "make test"
Code:
hello world
zlib version 1.2.5 = 0x1250, compile flags = 0x55
uncompress(): hello, hello!
gzread(): hello, hello!
gzgets() after gzseek: hello!
inflate(): hello, hello!
large_inflate(): OK
after inflateSync(): hello, hello!
inflate with dictionary: hello, hello!
*** zlib test OK ***

- I rebuilt ardour doing the tests in messages above: all ok
but with all the stuff that links on it, it'll surely require some more tests (X works ).
EDIT: this seems to be the slackware-current packages that contain thingies that link to libz.so.1
So, I tried to attack my specific problem with libxml2/zlib/ardour on x86_64. It took a rebuild of libxml2 as well, but the aforementioned segfault on session open is gone. Great work, again!
