D has a major issue with segfaults! It always reports the

This tells me nothing about where the error occurred in *my*
program!
Dmd needs to be modified so that errors try to show from the
source code. This should be obvious the reasons, if it is not
possible, make it possible! There are no excuses why dmd
should make me go on an easter egg hunt when a seg fault
occurs.
Um,
That was just an example, the same type of output occurs with
segfaults or any error/crash that D outputs stuff trying to be
"helpful".
Anyways, your missing the point. You expect me to write
try/catches in every level of my program to create the
granularity one needs to simply get the location the error
occured in? Where is that exactly?
How hard is it for dmd to know if
std.file.FileException@std\file.d occurs in the code I created or
somewhere else? It should be able to say "Hey, that is part of a
standard library or other non-user component, let me try to walk
back a little and see if I can find a location in the user code
that led to this problem".
This should be quite easy with a stacktrace, simply walk back
until the location is in user code.
So, regardless of anything, D telling me stuff like "Hey, your
error occurred in phobos" doesn't tell me shit except the error
occurred in phobos. I'm still looking for easter eggs, and I
don't like easter(which is why I don't capitalize it).
