Summary: Internal compiler error using std.algorithm.count with
recursive nested function in release.
Product: D
Version: D2
Platform: x86_64
OS/Version: Mac OS X
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: peter.alexander.au gmail.com
04:44:05 PDT ---
Compiling the following produces the error at compile time: "Internal error:
toir.c 190"
import std.algorithm;
import std.range;
void main()
{
int foo(int i) { return i == 1 ? 1 : foo(1); }
auto x = count(map!foo(iota(1, 2)), 1);
}
Only happens when:
- foo is recursive
- foo is a local function (doesn't happen if it is global)
- when using count (calling the function alone, or just mapping is fine)
- when compiling with (-inline)
If any one of these conditions isn't met then the code compiles as expected.
Note that while I have only noticed that std.algorithm.count causes this
problem, and std.algorithm.map doesn't, I haven't tested any other algorithms.
I'm using DMD 2.047.

Mass migration of bugs marked as x86-64 to just x86. The platform run on isn't
what's relevant, it's if the app is a 32 or 64 bit app.

With 2.059, no error occurs for the original case.
The errors in the other cases are legitimate, and are different.
