--- Comment #2 from Vladimir Panteleev ---
Domingo, can you try removing "public" from the imports in each module? I think
that's what's causing the slowdown.
I can reproduce the problem (and arrive at the same bisect result) with the
following synthetic test case:
// a.d /
public import a;
public import b;
.
public import y;
public import z;
Then copy a.d to b.d, c.d, ..., z.d.
You can use the following program to generate the test files:
/ gen.d
import std.stdio;
enum last = 'z';
void main()
{
for (char c = 'a'; c<=last; c++)
{
auto f = File(c ~ ".d", "w");
for (char c2 = 'a'; c2<=last; c2++)
f.writefln("public import %s;", c2);
}
}
Running `dmd a.d` will take a very long time.
Introduced in https://github.com/D-Programming-Language/dmd/pull/2448 (between
2.063 and 2.064.2).

--- Comment #2 from Nils ---
Another test case by monarchdodra showing that the overflowed value can be
greater than the original (duh):
import std.conv;
import std.exception;
void main()
{
auto s = "123";
assertThrown!ConvOverflowException(s.parse!ubyte(16)); /* fails */
}

[Issue 13152] [REG2.064.2] Compiler high cpu usage and never ends
https://issues.dlang.org/show_bug.cgi?id=13152 --- Comment #3 from Domingo Alvarez Duarte --- Yes removing the "public" attribute seems to allow dmd to work as expected. I saw that you've marked the commit that create this bug with a comment about this. So this will be a bug ? How can we describe it better ? --
[Issue 13166] New: pause and resume threads
https://issues.dlang.org/show_bug.cgi?id=13166 Issue ID: 13166 Summary: pause and resume threads Product: D Version: D2 Hardware: x86_64 OS: All Status: NEW Severity: enhancement Priority: P1 Component: Phobos Assignee: nob...@puremagic.com Reporter: sycam@gmail.com the core.thread class should have some mechanism for pausing or resuming threads or alternately should expose the OS thread handles so we can use OS specific thread functions (Not Advised) on windows it would be a wrapper for suspendthread and ResumeThread however on POSIX you would have to implement your own mechanism for doing so as pthread doesn't provide any such mechanism. --
