I turned off compilation optimization of mingw::lilypond as follows.
https://github.com/trueroad/gub/commit/1a6bc45fc00fa326270f2be40a5f588083e9db75

As a result, std::bad_alloc didn't occur any more.
But it was the following error.

test.ps lilypond generated was broken.
test.pdf was also broken of course.
