           Summary: call to wrong opEquals when trying `new Myclass==new
                    Myclass`
           Product: DGCC aka GDC
           Version: 0.21
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: glue layer
        AssignedTo: dvdfrdmn@users.sf.net
        ReportedBy: maniel.rulez@gmail.com


% gdc test.d rational.d -o test
% ./test
auto a = new Rational(1,2);
auto b = new Rational(1,3);
a>b: true
a<b: false
int opEquals_r(Object o): a==b: false
int opEquals(real x): 0.5==a: true
int opEquals(real x): a==0.5: true
int opEquals_r(Object o): a == null: false
int opEquals_r(Object o): null == a: false
% dmd test.d rational.d
gcc test.o rational.o -o test -m32 -lphobos -lpthread -lm
% ./test
auto a = new Rational(1,2);
auto b = new Rational(1,3);
a>b: true
a<b: false
int opEquals(Object o): a==b: 0
int opEquals(real x): 0.5==a: 1
int opEquals(real x): a==0.5: 1
int opEquals(Object o): a == null: 0
int opEquals(Object o): null == a: 0

(this is an output of my testcase)

I'm implementing rational fractions class in D and i found this bug(?). When i
remove `int opEquals_r(Object o)` method the gdc compiled version tries to use
int opEquals(real x) when i'm trying a==b (both Rational type), and this
generates a segfault while dmd compiled version works ok:>

I cannot reproduce the problem.

Did you build from source or use the binaries?  If the former, please try the binary package.  If you still have the problem, please post the exact source and command line that generates the crash.  Also, please post a backtrace.

Thanks!

Ech, i'm sorry, just noticed it was my fault, there was some rational.{d.23.greg,di,o} files laying in my home directory [wtf is this raional.d.23.greg file?:P] where i was compilong this test program...:) After i deleted them i've noticed that good opEquals methods are called and everythiong is ok:) Sorry for a problem:P Issue marked as WORKSFORME:)
