From d3def2ccdd0e1f25f4966eee8cfc4396861e4fb4 Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Thu, 6 Jan 2011 12:40:29 +0000 Subject: [PATCH] main: Record and print full exception stack traces. This turns on stack trace recording unconditionally (the same effect as if OCAMLRUNPARAM=b was always supplied), and also prints stack traces to the log file if there is an exception.
