Description:	Loaded symbols for /usr/lib64/libXdmcp.so.6 Core was generated by `asterisk -vvvvvvvvvvvvvvvvvgc'. Program terminated with signal 11, Segmentation fault. #0  0x0000000000000000 in ??

(gdb) ****** ADDITIONAL INFORMATION ****** As soon as I start my sipp simulator, 3 minutes later it crashes. I compiled it with all the debuggin options and I get thousands of lines of this: res_odbc.c line 451 (ast_odbc_request_obj): Deadlock? waited 75 sec for mutex '&(&class->odbc_obj)->lock'? res_odbc.c line 451 (ast_odbc_request_obj): '&(&class->odbc_obj)->lock' was locked here. I am using Freetds and unixODBC, how do I troubleshoot this?
Comments:	By: Tilghman Lesher (tilghman) 2008-01-05 00:41:44.000-0600 1) NEVER compile with all debugging options unless either a) you know what you're doing, or b) you are directed by a developer to do so. 2) Please recompile with ONLY the flags DONT_OPTIMIZE and DEBUG_THREADS.  When the problem occurs, please run the command "core show locks" and upload the output AS A FILE to the file upload area of this issue. By: Private Name (falves11) 2008-01-05 00:53:34.000-0600 The messages about locking did not appear, but I got this. Core was generated by `asterisk -vvvvvvvvvvvvvvvvvvvvvvgc'.

By: Tilghman Lesher (tilghman) 2008-01-05 01:32:48.000-0600 Please upgrade to the latest SVN trunk.  I cannot do anything with any of these backtraces.  They are useless for debugging.  "core show locks" is what I need to see. By: Tilghman Lesher (tilghman) 2008-01-05 01:47:18.000-0600 You could also try running under valgrind, by following the instructions in doc/valgrind.txt. By: Private Name (falves11) 2008-01-05 01:51:38.000-0600 The latest trunk fro svn does not compile in my machine, 64 Bit Rhel 5. The previous version did compile fine (94662). Please see latest file uploaded. I do this ./configure make menuselect (debug threads and don't optimize) make (here fails) make install By: Tilghman Lesher (tilghman) 2008-01-05 01:58:31.000-0600 Please install the libportaudio-dev package on your machine. By: Private Name (falves11) 2008-01-05 02:07:39.000-0600 Ininstalled portaudio, and compiles just fine, but Asterisk still does not. Please look at the latest file. The error is different. By: Tilghman Lesher (tilghman) 2008-01-05 02:14:20.000-0600 You have a very odd system that is letting you pass configure checks for packages that you do not have.  What system/distribution are you running? In this case, you need to install the package libiksemel-dev. By: Private Name (falves11) 2008-01-05 02:41:54.000-0600 I installed and compiled the latest version 94665, but it does not load. The previous version 94662 was loading fine. Asterisk SVN-trunk-r96645, Copyright (C) 1999 - 2007 Digium, Inc. and others.

This the GDB trace, and I don't know where the problem is. I need help using valgrind, if it is applicable.
