Note that MSVC usually has the debugging information in a separate
file, while GCC includes it in the binary. This could account for the
difference. However in release mode, in my experience, the GCC build
is smaller compared to the MSVC build. This is using GCC on Linux, but
I don't expect to make that much of a difference. So, if this is a
release build, then the results seem really odd to me.
