Hi Mike,
Thanks for the reply. Just tried to set DTRACE_DOF_INIT_DEBUG and rerun the command: bash-3.2$ songbird --version dtrace DOF libCrun.so.1: DTrace ioctl succeeded for DOF at fef7aa68 dtrace DOF libmozjs.so: DTrace ioctl succeeded for DOF at fec0eb30 POTI, Inc. Songbird 0.7.0, Copyright(c) 2005-2008 POTI, Inc. dtrace DOF libmozjs.so: DTrace ioctl removed DOF (0) Segmentation Fault (core dumped) However, it works fine for Firefox on the same box(different XULRunner) bash-3.2$ firefox --version dtrace DOF libCrun.so.1: DTrace ioctl succeeded for DOF at fef7aa68 dtrace DOF libmozjs.so: DTrace ioctl succeeded for DOF at f8a7aad0 Mozilla Firefox 3.0.1, Copyright (c) 1998 - 2008 mozilla.org dtrace DOF libmozjs.so: DTrace ioctl removed DOF (0) dtrace DOF libCrun.so.1: DTrace ioctl removed DOF (0) -Alfred _______________________________________________ dtrace-discuss mailing list [email protected]
