Hm. This trace says that the crash happened somewhere down inside ICU
itself, during the ucol_open() call in get_collation_actual_version().
There isn't much we could have done to mess up the arguments to that
function. That would seem to mean that it's ICU's bug not ours.
Maybe another reason not to be using such an old ICU version :-(.
I would like to test this with a newer ICU version.
So I managed to setup the build environment with Visual Studio, but I can't figure out how to enable ICU for the build.
Ah, figured it out.
config.pl has a different format compared to config_default.pl
$config->{icu}='d:\Projects\postgres\libs\icu'
did the trick, and postgres was built with ICU support.
I can confirm that with ICU 65 the crash does not occur and the case insensitive comparison works fine as well.
