OSX Sierra test fail, with master.

Hi

I am currently testing master on OS-X Sierra, with release settings (nearly):
--enable-debug
--enable-release-build
--with-distro=LibreOfficeMacOSX
--with-vendor=The Document Foundation
--disable-dependency-tracking
--disable-firebird-sdbc
--with-export-validation

the —enable-debug do not make any difference.

When I do just “make” I get:
http://pastebin.com/QcR0vgVU <http://pastebin.com/eeyBuwh5>

it comes in CppunitTest_sw_rtfimport, but after the stack trace the build process hangs, and need a 
kill -9 to go away.

the essence begin:
warn:writerfilter:39743:1:writerfilter/source/dmapper/DomainMapper.cxx:133: 
DomainMapper::DomainMapper: failed to initialize RDF metadata: component context fails to supply 
service com.sun.star.rdf.URI of type com.sun.star.rdf.XURI
warn:legacy.osl:39743:1:oox/source/helper/graphichelper.cxx:117: GraphicHelper::GraphicHelper - 
cannot get target frame


fdo43965.rtf:

for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug




Now since this was a cppunit test, I thought to do a second build “make build-nocheck”, that gives 
me
http://pastebin.com/y6ShA7NN <http://pastebin.com/y6ShA7NN>

First error:
warn:writerfilter:39743:1:writerfilter/source/dmapper/DomainMapper.cxx:133: 
DomainMapper::DomainMapper: failed to initialize RDF metadata: component context fails to supply 
service com.sun.star.rdf.URI of type com.sun.star.rdf.XURI
warn:legacy.osl:39743:1:oox/source/helper/graphichelper.cxx:117: GraphicHelper::GraphicHelper - 
cannot get target frame


the essence being:
warn:sfx.sidebar:39743:1:sfx2/source/sidebar/SidebarController.cxx:857: Cannot create panel 
private:resource/toolpanel/SvxPanelFactory/ParaPropertyPanel: 
fdo43965.rtf:

It seems to me we have a memory fault, in graphic helper, or am I completely wrong ?

I will repeat the test with 5.2, just to see if it is an old problem.

Thanks in advance for any advice.
