Attempting to run the accumulators regression test on the trunk, using 'bjam toolset=gcc-4.5.2' ( MingW/gcc-4.5.2 ) is giving me a number of pop-up Windows in Vista saying that "cc1plus.exe has stopped working". Cc1plus.exe is the gcc compiler under MingW. In the output there are a number of failures. Does anybody know why this is occuring ?
