Hi, everyone

I have tired to compile boost from boost_1_81_0 to boost_1_88_0 with MSYS2 by getting source code from https://www.boost.org/releases/latest/

And I got two kinds of result:
(1) That is fine to be compiled from boost_1_81_0 to boost_1_84_0;
(2) but there is some problem from boost_1_84_0 to boost_1_88_0.

Before (2), I already run: ./bootstrap.sh --with-toolset=gcc --with-libraries=all --prefix= successfully.

So, the question is why the compilation problem happen and how to fix it ?

Thanks a lot !

Could the problem be in --prefix=? Try a non-empty prefix.
