9560	operations_test_static unit test crashes during static initialization phase on Mac/10.7/32-bit/darwin-4.2.1	Monty Brandenberg <mcbinc@…>	Beman Dawes	"Verifying a 32-bit build of Boost on Mac, I get a consistent crash in operations_test_static during static initialization (prior to main() invocation).  Problem appears to be a lack of initialization of path.hpp's anon namespace 'codecvt_facet_ptr'.

Platform:  1.55.0, Mac OS 10.7, Xcode 4.3.3, darwin-4.2.1,
address-model=32, architecture=x86

Build sequence is (approximately):

{{{
./bjam toolset=darwin variant=debug address-model=32 architecture=x86 --layout=tagged --with-filesystem -sNO_BZIP2=1 -d2 -d+4 stage
cd libs/filesystem/test
../../../bjam toolset=darwin variant=debug address-model=32 architecture=x86 --layout=tagged --with-filesystem -sNO_BZIP2=1 -d2 -d+4 -a -q
}}}
