Our workaround we currently use to cope with issues cross-compiling rustc for 32bit Windows us not upstreamable (see: for the arguments). We could think about compiling with a mingw-w64 using dwarf exception support instead, see: (

However, we should take into account that we want to switch to a mingw-w64/clang-based toolchain soon and should start looking into this ticket not before the other (#28238) is done.
