          Issue ID: 24645
           Summary: Hidden static assert error messages if more than 20
                    errors
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com

Imports are processed by frontend before static asserts. As result, for simple
example (two lines of code only):

static assert(false, "some assertion failed");
import core.stdc.stdatomic;

user during compilation isn't sees any static assert error messages:

> ldc2 --mtriple=riscv32-unknown-newlib-elf -c assertion_test_main.d
/home/denizzz/ldc2_standalone/bin/../import/core/stdc/stdio.d(31): Error:
module `core.stdc.stdint` import `intptr_t` not found
/home/denizzz/ldc2_standalone/bin/../import/core/stdc/stdio.d(798): Error:
module `core.sys.posix.sys.types` import `ssize_t` not found, did you mean
alias `object.size_t`?
/home/denizzz/ldc2_standalone/bin/../import/core/stdc/stdio.d(802): Error:
undefined identifier `c_long`
/home/denizzz/ldc2_standalone/bin/../import/core/stdc/stdio.d(2011): Error:
module `core.stdc.stddef` import `wchar_t` not found
[~16 lines skipped]

With --verrors=0 option user able to see appropriate static assert line at the
end of compiler output, but it's confusing because it's unexpected not obvious
behaviour

Is it possible to move static errors messages higher?
