use miniruby or set it to other released version ruby as "--with-baseruby" option or "BOOTSTRAPRUBY"
is same error occur.

if use miniruby at use tool/mkconfig.rb or generate ext/configure-ext.mk would have chance to occur: Errno::EBADF error

at 4.0.0-preview2 was compiled OK.

ENV:
windows 10~11
msys 1.0 && gcc 7 ~ 12 for test
the environment and toolchain is nothing wrong because i compiled 3.1 to 4.0 preview 2 in this environment.
