Hello,

I faced with strange issue on MacOS, when I tried to open file more then 1 Gb:
It've got an error:
std.exception.ErrnoException std/stdio.d(545): Cannot open file `DTM.NDS' in
mode `rb' (No such file or directory)
----------------
??:? _D3std9exception__T7bailOutHTCQBcQBb14ErrnoExceptionZQBiFNfAyamMAxaZNn

??:?  safe shared(core.stdc.stdio.__sFILE)*

This troubles are present in many versions of DMD: 2.067-2.098.


I've tried to open this file via another languages (C++/Kotlin Native) using
the same C runtime (File operations) and everything worked perfect.

I was surprised that this simple methods didn't work properly, this means we
can't use DMD for serious project cause as I see current status of it is
semi-working.

The same situation with Socket, it doesn't accept connection (all versions  
after 2018), e.g. 2.066 working with socket well, but it has the same issue
with opening big files...
