Fine till this. I assume at this stage the unit tests of <module> is
executed, and that will show up in the report. I tried this with
'writerfilter', then executed 'cd sw; make -sr slowcheck', which
executes the tests for writerfilter.

Seems this dies here with:

$ lcov -c -d workdir/
Capturing coverage data from workdir/
Found gcov version: 4.7.1
Scanning workdir/ for .gcda files ...
Found 113 data files in workdir/
Processing CxxObject/writerfilter/source/ooxml/OOXMLBinaryObjectReference.gcda
Out of memory!

Can you share what lcov switches did you use that worked for you? I get
this error ~instantly with 8G of ram, so it sounds a bit misleading.

Thanks,

Miklos
