llvm dev - Mar 2015 - [LLVMdev] Clang 3.5.1 assertion failure on FreeBSD when building LLDB

A change between r231216 and r231221 causes an assertion failure on
the LLDB FreeBSD bot. The compiler is FreeBSD's in-tree one: FreeBSD
clang version 3.5.1 (tags/RELEASE_351/final 225668) 20150115

First failing build:
http://lab.llvm.org:8011/builders/lldb-x86_64-freebsd/builds/4668/steps/compile/logs/stdio

Assertion:
Assertion failed: ((!DD->isTrivial() ||
DD->hasAttr<DLLExportAttr>())
&& "Should not emit dtor epilogue for non-exported trivial
dtor!"),
function EnterDtorCleanups, file
/usr/src/lib/clang/libclangcodegen/../../../contrib/llvm/tools/clang/lib/CodeGen/CGClass.cpp,
line 1429.

Galina, is it possible to get the /tmp/CommandLine-26c092.cpp and .sh
from the bot?

Hi Ed,

I'm already investigating it, as it broke our buildbots, too.

cheers,

I'm seeing the same when building llvm trunk with clang 3.6.

The bug also has a creduced test case.
