Invalid string construction in ifc::util::(anonymous namespace)::ExprLoader::operator()

[aytey]

Issue

I am trying to print (using ifc-printer) the "header unit" IFCs for some standard headers (e.g., vector). These have been generated as follows:

cl.exe /std:c++latest /exportHeader /headerName:angle /EHsc /MD ${NAME}

For the following files:

chrono.ifc
compare.ifc
concepts.ifc
coroutine.ifc
cstddef.ifc
initializer_list.ifc
iterator.ifc
numbers.ifc
random.ifc
ratio.ifc
type_traits.ifc
xlocinfo.ifc

They all crash with the following stack trace:
