💔 Test failed - checks-actions

It looks like it needs the latest GCC or Binutils to work.
Passes locally with toolchains provided by MSYS2 but fails on CI with older toolchain:

  ---- ptr::write_unaligned_drop stdout ----
  ---- ptr::write_unaligned_drop stderr ----
  note: got unexpected return code -1073741819

FWIW previously I had did only stage1 which is not enough to test spec changes. Reran the test locally with stage2 and it still works. So indeed, enabling this is just the matter of waiting an unspecified amount of time before minimal versions for GCC+Binutils+mingw-w64 can be set high enough.
