From c33bd9aac0597eeedaaa01ea5aafe456894b2f2b Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Mon, 26 Jun 2006 13:57:47 +0200 Subject: [PATCH] i386/x86-64: fall back to old-style call trace if no unwinding If no unwinding is possible at all for a certain exception instance, fall back to the old style call trace instead of not showing any trace at all. Also, allow setting the stack trace mode at the command line.
