Hi all, As a few people have noticed, when you build trunk on Mac OS X with optimization enabled, g++ gets an internal compiler error. This seems to be caused by generating debug info ... you can work around it by removing the "-g" from CXFLAGS or disabling optimization by adding "-O0".
In the medium term, we ought to switch to clang for building on OS X. I think this will require flipping AC_PROG_CC and AC_PROG_CXX to search for "c++" before "g++". Are there platforms that we support for which this is not desirable? J
