ok, so I rebuilt using noDebug and still no symbol table, but I ran gdb inside the csound5 build directory and I got this: (gdb) run Starting program: /home/hector/build_backup/Csound_CVS/csound5/csound [Thread debugging using libthread_db enabled] [New Thread -1209055552 (LWP 12027)] Program received signal SIGSEGV, Segmentation fault.

But I don't know if reflects the same problem since it's running the binary inside the build folder and not the installed one.
