http://d.puremagic.com/issues/show_bug.cgi?id=7883 Summary: Compiler crashes with double inheritance and function contract Product: D Version: D2 Platform: x86 OS/Version: Windows Status: NEW Severity: normal Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: dlang grotmol.net --- Created an attachment (id=1087) Test case crashing the compiler Class C inherits from B which inherits from A. All three classes define the same function. A and B specifies an out contract on the function (C may or may not specify an out contract, it doesn't matter). In this case, dmd crashes without error message, and doesn't generate the .exe file. Here is the verbose output: $ dmd -v e binary C:\D\dmd2\windows\bin\dmd.exe version v2.058 config C:\D\dmd2\windows\bin\sc.ini parse e importall e import object (C:\D\dmd2\windows\bin\..\..\src\druntime\import\object.di) semantic e semantic2 e semantic3 e At this point it just stops. The rest of the output should have been as follows, if I remove one of the two contracts: code e function e.A.foo function e.A.foo.__ensure function e.B.foo function e.C.foo function D main C:\D\dmd2\windows\bin\link.exe e,,nul,user32+kernel32/noi; -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=7883 ---It compiles and runs on DMD 2.059 Win32Hi, Could you check this one also please? By mistake the file I uploaded had commented out one of the contracts, and then the file does indeed work. It is only when both contracts are in place, that dmd crashes. class A { int foo(int i) out (result) { } body { return 1; } } class B : A { int foo(int i) out (result) { } body { return 1; } } class C : B { int foo(int i) { return 1; } } void main() { } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
