Reading "Value Range Propagation" further down that link, I learned that
e.g. masking 'decimal' with 0xf makes the code compile:
return ((decimal & 0xf) + ubyte('0'));

Yes. It is called integer promotions:

The workaround is to compile without --release mode, but using
the "O3" ldc flag instead does the job - the binary is fast, yet
the try - catch block executes properly.

OK, got the problem solved by adding the following lines in my
dub.sdl file:
lflags "-lopenblas" "-lgfortran"
dflags "--static"
However, one problem still remains. Apparently, when compiled
with dub --release mode I got segfault in my try - catch block.
Any solution to this?

Looks like explicitly initialized variable in this case allocates
array literal. Uninitialized variable is initialized with init
pattern. This may be correct as uninitialized variable isn't
guaranteed to hold a value most useful for you, it's only
guaranteed to hold a defined value.
I am now trying to compile the code statically using the dub

dub build --force --build=release --compiler=path_to_ldc2/ldc2

As a result, if this is a bug, Andrey has the right to report
