GCC 11.2 crashes with ICE on any usage of certain STL headers as header units, e.g.: filesystem, memory, regex etc.
using libc++ instead of libstdc++ does not help
producing header units for each STL header beforehand does not work, ICE happens already on creating the above header units
using them all via textual include and exporting them in a bundle produces the module successfully but any usage of it fails with ICE (bad module data)
