           Summary: dmd crashes while compiling
           Product: D
           Version: D2
          Platform: All
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: phyphor0 gmail.com



One source file:

import std.stdio;
void main() {}


Compile with the following command line:

dmd -noboundscheck -inline -release -deps=temp.dep main.d

All arguments are needed, as is the import. main() is not.

Version 2.057

It is crashing in AttribDeclaration::inlineScan(),

        for (size_t i = 0; i < d->dim; i++)
        {   Dsymbol *s = (*d)[i];
            s->inlineScan();  //   <---- crashes here

It isn't a null pointer, it seems to be an invalid vtable (memory corruption?)

I can reproduce this on Windows7, but not on Linux64.

This is the worst heisenbug I've ever seen. Although it's possible to reduce
the test case a bit, the reduction makes no sense -- changing an unused list of
anonymous enums from 9 to 8 items makes the bug go away, for example.

It seems to be either a stack overflow or an out of memory condition, because
the faulting location jumps around if you make changes to the test case.

Worse, some changes don't just crash; they cause the windows command prompt to
hang afterwards.

Bug 6951 seems to be the same as this one.
