[Issue 18026] Stack overflow in ddmd/dtemplate.d:6241, TemplateInstance::needsCodegen()

[d-bugmail--- via Digitalmars-d-bugs]

https://issues.dlang.org/show_bug.cgi?id=18026

--- Comment #6 from JR  ---
I can no longer reproduce with 2.079.1 nor 2.080.0, on the same machines that
previously exhibited the overflow.

Was something changed, or is it merely being tricky again?

[Issue 18822] [REG 2.080.0] Compiling byGrapheme Fails

[d-bugmail--- via Digitalmars-d-bugs]

https://issues.dlang.org/show_bug.cgi?id=18822

--- Comment #1 from Jack Stouffer  ---
Introduced in https://github.com/dlang/phobos/pull/6235

So, what's happening is that the toString of Appender now uses formatValue,
which calls formatRange, which calls graphemeStride. Grapheme uses TrieBuilder,
which uses std.conv.text for an error message which uses Appender, and you can
see the problem.

[Issue 18819] DMD compilation crash

Disregard, there's no 0-sized type in there, and DMD obviously shouldn't crash
anyway.

[Issue 18820] New: dip1000 mangling is different for inferred templates

[d-bugmail--- via Digitalmars-d-bugs]

https://issues.dlang.org/show_bug.cgi?id=18820

  Issue ID: 18820
   Summary: dip1000 mangling is different for inferred templates
   Product: D
   Version: D2
  Hardware: All
OS: All
Status: NEW
  Keywords: link-failure, safe
  Severity: normal
  Priority: P1
 Component: dmd
  Assignee: nob...@puremagic.com
  Reporter: schvei...@yahoo.com
CC: bugzi...@digitalmars.com

If a template/auto function has attributes inferred, and you compile a module
with dip1000 and another module without, the mangling may depend on new
attributes inferred by dip1000, which makes it impossible to link.

Example:

- mod2.d:
module mod2;

auto foo(T)(T s) @safe
{
return s;
}

auto foo2(scope string s)
{
return foo(s);
}

- mod1.d:
module mod1;
import mod2;

void main()
{
scope string s;
auto x = foo2(s);
}

If we compile like this:
dmd -c mod2.d
dmd -dip1000 mod1.d mod2.o

We have linker errors.

Compiling both together works:
dmd mod1.d mod2.d
dmd -dip1000 mod1.d mod2.d

The fundamental problem here is that it makes dip1000 NOT an optional switch,
but a required switch. So if we plan to ship with dip1000, it will force
everyone not only to use dip1000, but to make sure ALL their code (including
code they may not control) to use dip1000.

I don't know a solution to this other than to ship 2 libraries.

Walter asked me to add this so there is a bugzilla report about it.
