I've tried to reduce this down to a smaller case, but using -save-temps resulted in a file which does not manifest the problem. But then, maybe it shouldn't have.
My project is publically avaliable at http://github.com/jwiegley/ledger. Perhaps this is too oblique, but if you pull the project and run "./acprep make --no-patch --pch", it will generate a Bus Error when compiling as follows (assuming you have Boost, GMP and MPFR devel libraries installed as well): libtool: compile: /opt/local/bin/g++-mp-4.4 -DHAVE_CONFIG_H -I. -I/Users/johnw/Projects/ledger -I/Users/johnw/Projects/ledger/src -I/Users/johnw/Projects/ledger/lib -I/Users/johnw/Projects/ledger/lib/utfcpp/source -isystem /usr/local/include -isystem /usr/local/include/boost-1_38 -isystem /usr/local/include -isystem /usr/include/python2.5 -isystem /opt/local/include -isystem /usr/local/stow/cppunit/include -fpch-deps -Wconversion -ansi -Wall -Winvalid-pch -Wextra -Wcast-align -Wcast-qual -Wfloat-equal -Wmissing-field-initializers -Wno-endif-labels -Woverloaded-virtual -Wsign-compare -Wsign-promo -Wstrict-null-sentinel -Wwrite-strings -Wno-old-style-cast -Wno-deprecated -g -pipe -MT libledger_report_la-stats.lo -MD -MP -MF .deps/libledger_report_la-stats.Tpo -c /Users/johnw/Projects/ledger/src/stats.cc -o libledger_report_la-stats.o cc1plus: internal compiler error: Bus error Please submit a full bug report, with preprocessed source if appropriate.
