[Libreoffice] Master build Seg faults in starmath test

[John LeMoyne Castle]

I have pulled and built a couple of times in the last few days with a make
clean in between on master. 
Was able to build in master on 28.5.2011 - now not so much 
I am getting a consistent failure at this point...

Other info:
.../workdir/CppunitTest/starmath_qa_cppunit.test.log is empty.

This run is with:
/starmath$ export DEBUGCPPUNIT=TRUE
/starmath$ make -r debug=true dbglevel=1 > make.log

Have tried --with-num-cpus=1 because my older machine sometimes seems to
have parallelism problems but no other ./autogen.sh options

This log shows failure in ServerFontLayoutEngine::operator() -- 
previous runs showed seg fault (a little further along?) in GetGlyphData. 

I am unclear if this is related to code from the recent merge or build
configuration or headless mode or something else. 
Days of building with consistent failure in tail_build are getting me down,
because it is all (or nearly all) built at the point where this unit test is
failing
Any help would be immensely appreciated, 
LeMoyne
