Summary: compiler segfaults
Product: D
Version: 1.056
Platform: Other
OS/Version: Mac OS X
Status: NEW
Severity: regression
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: fawzi gmx.ch
The following (incorrect) code segfaults the compiler
I suppose that it is connected with something segfault on correct code of
{{{
struct S {
int x;
template T(int val) {
const P T = { val }; // the P here is an error it should be S
}
}
template V(R,int val){
const R V=R.T!(val);
}
const S x = V!(S,0);
}}}

This was a regression since 1.053. Suprisingly, it is fixed by bug 3767, in svn
367.

I have tried to find the problem using ldc (that shares the problem), also
using the larger correct code that shows the problem (stacktraces are similar).
The problem seems to be located in expression.c:5048
Dsymbol *s = ti->inst->toAlias();
ti->inst == NULL, so that the compiler segfaults.
In the correct code I am not sure if inst is NULL because a single pass cannot
instantiate the template, or because it is in an is expression.
In any case simply catching this case and return new ErrorExp(); doesn't seem
to be enough (then I have other problems).

a clean compile, and my fix doesn't look to bad.
klickverbot even tested dstess, and it did not make anything worse.
It might not be the correct fix, but still improves things.
