From 251669654ae50bb6b39f71a6524c152123e2bcc8 Mon Sep 17 00:00:00 2001 From: markj Date: Fri, 28 Aug 2015 00:38:18 +0000 Subject: Re-apply r274569. It was reverted in r276848 since that appeared to fix some ctfmerge crashes that started to occur on i386 weeks after r274569 was committed. Some later investigation indicated that the crashes were caused by malformed CTF info that led to a stack overflow. The issue with CTF info in i386 kernels seems to have been resolved by r261246, which updated libdwarf and libelf. r274569 fixes a bug which caused duplicate types to appear in the kernel's CTF info. This duplication generally does not cause problems when using DTrace, but makes it easier to hit the limit of 2^15 - 1 distinct type definitions in a CTF container.
