Both mingw64-x86_64-icu-57.1-1 and mingw64-x86_64-icu-57.1-2 are broken:
This code always fails:
icu::Normalizer2::getInstance(nullptr, "nfkc", UNORM2_COMPOSE, error_code);
The problem was detected when comparing Tesseract for Windows
executables: while the 32 bit version worked fine, the 64 bit version
failed. The failure could be localized, and the mingw64-x86_64-icu
package was identified to be causing it.
https://github.com/tesseract-ocr/tesseract/issues/1625#issuecomment-395161152
contains details and also a short test code which can be used to
reproduce the problem.
The 32 bit package mingw64-i686-icu-57.1-2 works fine.
Kind regards
Stefan Weil

Ping. How can I help to get this issue fixed?

I noticed cygport is using llvm version of binutils, not sure if that
broke things.
Was the issue there if you built it yourself with gcc/binutils?

No, a local build with x86_64-w64-mingw32-gcc works fine.
Tested with 57.1-2, but also with recent versions of icu.
A good indicator of a broken installation is a small icudata57.dll:
$ ls -l /usr/*/sys-root/mingw/bin/icudata57.dll
-rwxr-xr-x 1 25680896 Nov 10 2016
/usr/i686-w64-mingw32/sys-root/mingw/bin/icudata57.dll
-rwxr-xr-x 1 15872 Nov 10 2016
/usr/x86_64-w64-mingw32/sys-root/mingw/bin/icudata57.dll
The (good) file for 32 bit is much larger than the (broken) file for 64 bit.

The cygport post-install debug strip is probably stripping too much.
Whoever the maintainer of this package can do a test rebuild with llvm-*
binutils temporarily moved away as a test if Cygport is used.
