           Summary: Throwing exception in finally block hides original
                    exception
           Product: D
           Version: 2.041
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

The message for assertion "a" will never be displayed, even though it certainly fails:

void main() {
    try {
        assert(false, "a");
    } finally {
        assert(false, "b");
    }
}

Executing this program should display messages for both cases. Otherwise, it may be impossible to tell what actually failed: assertion b may depend on cleanup code that was supposed to be executed after assertion a. It is not unusual that other, seemingly unrelated, assertions fail once the program's state is "corrupted".

Suggested fix: link the exceptions via Throwable.next.

This is an important matter. We don't want under any circumstances to irretrievably lose information. nfxjfg@gmail.com, I understand you may be frustrated by the slow response, but please don't undo the valuable work you've put into reporting these bugs. Thanks.

It's particularly ironic -- this bug was actually fixed.
(Fixed in DMD 2.048).
