digitalmars.D.bugs - [Issue 17308] New: [TEST/PROCESS] Beta releases should not be built


          Issue ID: 17308
           Summary: [TEST/PROCESS] Beta releases should not be built with
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd

The quality of assertions just seems to be going downhill post conversion to D.


I squinted with mistrust at this line for a full 5 minutes.
assert(cdto.sizeok == SIZEOKdone || !cdto.isBaseOf(cdto, null))

Assert that `cdto' has had it's size determined, or that `cdto' is *not* a base
class of... itself?  Hmmm... surely that would be identical to having.
assert(cdto.sizeok == SIZEOKdone || true)

Which is identical to having.

At which point, one begins to wonder what on earth is this doing here if it's a

If beta releases are compiled with -release, IMO they shouldn't be, as lots of
bugs are falling through the gaps.  The frequency that I'm getting assertion
failures in code backported from D is just unnerving.

Some past examples include.

Change: https://github.com/dlang/dmd/pull/5875
Asserts with: extern(C++, ...) void ice();

Change: https://github.com/dlang/dmd/pull/5972
Asserts with: struct BitRange { this(size_t) { } }

Change: https://github.com/dlang/dmd/pull/6065
Asserts with: struct DSO { MG mg; }  struct TDSO { int a; DSO* b; }

All these examples are reasonably simple code tests, so can not imagine them
*not* being caught by beta testers.
