           Summary: Size of executable almost triples
           Product: D
           Version: 1.032
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: StefanLiebig@web.de


I recently had to fix a little bug in an D application (win32). I thought that
it would also be a good idea to upgrade to the most current version of the D
compiler.
When upgrading to 1.033 from 1.025 the executable size almost tripled from 227
kb to 603 kb! After building with all version from 1.025 up I found that this
phenomenon occurs when switching from 1.031 to 1.032. I did not change the
compiler options (-release, -o) when building with several dmd versions.
I saw the many changes/bugfixes from 1.031 to 1.032. However, can that explain
this behaviour?

Yes, every fixed bug increases your executable size by 5% <g>

1.032 is the first version where phobos.lib is built using the new -lib switch.
 That seems the likely culprit.

http://www.dsource.org/projects/phobos/changeset/811

I tried building hello world tests with dmd 1.031 and 1.032 to see the size differences:

Hello world with writefln (import std.stdio):
1.031: 114.4 k
1.032: 269.5 k

Hello world with printf (no imports):
1.031: 78.0 k
1.032: 121.5 k


So something bad definitely happened between 1.031 and 1.032.  Now, if someone could be bothered to try building phobos 1.032 without the -lib switch and compare, that would be great.

Comparing the two map files shows the difference comes from the first line:
 0002:00000000 000193FBH  _TEXT                  CODE 32-bit
vs
 0002:00000000 0000CC9BH  _TEXT                  CODE 32-bit

Yep, that did the trick. I've used the v1.031 makefile to build phobos from v1.032, using v1.032. Both phobos.lib and the built .exe file have the size from v1.031. It's definately the -lib switch that's causing the bloat.

I rebuilt my application with DMD 1.034 (where it should have been fixed) and
it has the same effect as before. It still triples. Can someone (maybe
torhu@yahoo.com) check that.

In which way is that fixed while there are reports in this ticked, after release of 2.018, that it's not fixed?

Probably you missed these comments...

I tried my hello world tests from comment #1 with dmd 1.034.  The file sizes are the same or slightly larger.

I'm not sure what fix Walter has made, but the original issue is still there.
