Visual Studio 2010, Intel Compiler version 18.104.22.168.
This problem occurs in debug builds.
If /debug:parallel is set, pdbxinst.lib is included. It has a defaultlib directive pointing to libcpmt. If any module compiled with _DEBUG set uses libcpmt, a LNK2038 error results for _ITERATOR_DEBUG_LEVEL.
The workaround of /NODEFAULTLIB:libcpmt.lib when linkingseems to work, but has unknown side effects.
Either a debug version of pdbxinst.lib that links to libcpmtd.lib should be supplied and used in this case, or the dependency on libcpmt needs removing.
