Bug 345635 – Asterisk segfaults when openh323 and pwlib were built using -Wl,--as-needed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Grigoriy Puzankin 2010-11-15 16:17:32 UTC]

Asterisk dumps core when loading chan_h323.so module compiled against emerged libraries pwlib and openh323 using -Wl,--as-needed.

I'm building Asterisk from original source code (1.6.2.x, 1.8.0) on x86_64. But it also happens on x86 platform too.


Reproducible: Always

Steps to Reproduce:
1. Emerge dev-libs/pwlib and net-libs/openh323 using -Wl,--as-needed (default).
2. Compile Asterisk with h323 support (bundled module chan_h323) against those libraries.
3. Asterisk dumps core when loading chan_h323.so module.

Adding block to http://bugs.gentoo.org/show_bug.cgi?id=129413

If you do not use the Asterisk ebuild, I can not support you.

[Comment 3 Grigoriy Puzankin 2010-12-01 18:25:24 UTC]

I have cleaned up previous Asterisk installation and built Asterisk from net-misc/asterisk-1.6.2.13-r2 ebuild. Trying to load chan_h323.so gives errors:

*CLI> module load chan_h323.so
Unable to load module chan_h323.so
Command 'module load chan_h323.so ' failed.
*CLI> [Dec  1 21:18:32] WARNING[18363]: loader.c:387 load_dynamic_module: Error loading module 'chan_h323.so': /usr/lib/asterisk/modules/chan_h323.so: undefined symbol: _ZNK7PObject7CompareERKS_

I know what it means. When building Asterisk from sources I can cleanup channels/h323 directory and rebuild chan_h323.so module, but not with ebuild.

Also building Asterisk from sources gives the same error when pwlib and openh323 compiled with --as-needed option.

[Comment 4 Tony Vroon (RETIRED) 2010-12-06 10:55:43 UTC]

There is no h323 support in the Asterisk ebuild as this is known broken. The only action I can take based on this bug report is to more aggressively obliterate the H323 support so that it never hits the disk.
(I still believe that the h323 module in question was produced by you and not the ebuild though)

[Comment 5 Tony Vroon (RETIRED) 2010-12-06 11:16:24 UTC]

Unless I hear otherwise (i.e. in the form of patches that enable a demonstrably non-broken H323 module without relying on packages that have been masked for removal), the newest Asterisk patch set for 1.6.2 will contain a removal patch for the H323 configure checks & build system components.
