           Summary: Win32 OPTLINK crashes when it links some kind of static
                    library into a executeable.
           Product: D
           Version: 2.018
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: link-failure
          Severity: critical
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: hskwk@inter7.jp


Windows dmd (later than 2.018) OPTLINK crashes (Unexpected OPTLINK termination)
when it links some kind of static library into a executable.
Here is a small example as a quick report.


---- make following module into a static library

module test;
import std.random;
Mt19937 gen;
uint nonThreadSafeRandom() {return gen.next;}


---- OPTLINK crashes when making following code into a exe with linking the
library just made before

import test;
void main() { uint a = nonThreadSafeRandom(); }

---- OPTLINK works if deeper module is imported

import test, std.random;
void main() { uint a = nonThreadSafeRandom(); }



This is a quick report, I have not found a true cause yet.

thanks,

p.s.
I'm sorry posting redundant news on digitalmars.D.bugs.
I wish this tracker is the proper channel to report bugs.

Commands I used in the first report

dmd -c test.d
lib -c -p32 test.lib test.obj
dmd main.d test.lib

causes crash described before.
following commands

dmd -lib test.d
dmd main.d test.lib

causes this error, regardless of importing std.random:
test.lib
 Warning 140: Library probably needs FIXLIB
--- error level 1



Only std.random causes this error, as I tested.

I can't duplicate the optlink crash, but I can the needs FIXLIB problem.

I'm not sure what the FIXLIB warning is about, but I think it can be safely ignored.

Warning removed in link 8.00.7, the crash is not reproducible.
