MAC OSX 10.6 scary build error: Segfault in the compiler

so after a fairly long hiatus.. I'm trying to get master build on Mac
OSX 10.6 SDK back into shape...

I've been running in python issue that seems to be related to a
--enable-system-expat in ./configure of python3

then WaE... about obsolete redland API... which I skipped for now..

but then I ran into:

[build CXX] unotools/source/ucbhelper/localfilehelper.cxx
/Volumes/TBRAM/build_core/unotools/source/misc/fontcvt.cxx:1538:
internal compiler error: Segmentation fault

gitk on that file does not show anything special.. a few
String/OUString patche recently.. but nothin that would ring a bell...

Apparently there is a new corollary to Murphy's law:

The amount of breakage in the build is inversely proportional to the
amount of free time you can consacrate fixing them....
