Problem originally found by tsukikage.
A handy printing function for BigInts is really needed in Phobos.
Have you tried writefln?
import std.stdio;
import std.bigint;
void main()
{
BigInt a = 7;
a ^^=56;
writefln(%x, a);
writefln(%s, a);
}

[Issue 4705] Redesign of std.algorithm.max()/min() + mins()/maxs()
http://d.puremagic.com/issues/show_bug.cgi?id=4705
--- Comment #6 from bearophile_h...@eml.cc 2011-02-13 05:51:55 PST ---
Two more usage examples of the improved max. This program finds the longest
common subsequence with a recursive algorithm:
import std.stdio;
T[] lcs(T)(T[] a, T[] b) {
T[] longest(T)(T[] s, T[] t) {
return s.length t.length ? s : t;
}
if (!a.length || !b.length)
return null;
if (a[0] == b[0])
return a[0] ~ lcs(a[1..$], b[1..$]);
return longest(lcs(a, b[1..$]), lcs(a[1..$], b));
}
void main() {
writeln(lcs(thisisatest, testing123testing));
}
With a key-mapping max() you are able to remove the inner function and simplify
the code (untested):
import std.stdio;
T[] lcs(T)(T[] a, T[] b) {
if (!a.length || !b.length)
return null;
if (a[0] == b[0])
return a[0] ~ lcs(a[1..$], b[1..$]);
return max!q{a.length}([lcs(a, b[1..$]), lcs(a[1..$], b)]);
}
void main() {
writeln(lcs(thisisatest, testing123testing));
}

This program shows the most common anagrams from a dictionary file of different
words:
import std.stdio, std.algorithm;
void main() {
string[][string] anags;
foreach (w; File(unixdict.txt).byLine())
anags[w.sort.idup] ~= w.idup;
int m = reduce!max(map!q{a.length}(anags.values));
writeln(filter!((wl){ return wl.length == m; })(anags.values));
}
A key-mapping max() makes the code shorter and more readable (untested):
import std.stdio, std.algorithm;
void main() {
string[][string] anags;
foreach (w; File(unixdict.txt).byLine())
anags[w.sort.idup] ~= w.idup;
int m = max!q{a.length}(anags.values);
writeln(filter!((wl){ return wl.length == m; })(anags.values));
}
maxs() simplifies the code even more (untested):
import std.stdio, std.algorithm;
void main() {
string[][string] anags;
foreach (w; File(unixdict.txt).byLine())
anags[w.sort.idup] ~= w.idup;
writeln(maxs!q{a.length}(anags.values));
}

Have you tried writefln?
import std.stdio;
import std.bigint;
void main()
{
BigInt a = 7;
a ^^=56;
writefln(%x, a);
writefln(%s, a);
}
I have never tried that. I suggest to add this example to docs of the
std.bigint module :-)
Yes, although I think it's pretty obvious. The non-obvious thing, is that if
you tried in on 2.050 or earlier, it didn't work... It does now.

[Issue 4014] CodeView debug type info not linked in from library
http://d.puremagic.com/issues/show_bug.cgi?id=4014 Walter Bright bugzi...@digitalmars.com changed: What|Removed |Added Status|RESOLVED|REOPENED Resolution|FIXED | --- Comment #3 from Walter Bright bugzi...@digitalmars.com 2011-02-13 11:41:55 PST --- Rainer Schuetze writes on the mailing list: trying to create a branch with as little changes to the master branch as possible, I noticed that this patch causes problems when creating DLLs (it still wants _Dmain to be defined). This is happening because the patch puts full modules into a library instead of single functions when also adding debug symbols, so any reference into rt.dmain2 drags in the standard console application startup. My patches to create a shared version of the runtime library split this module, so the issue did not show up before. I'd say the patch to 4014 should be reverted until this is sorted out. A minor improvement could be that prohibiting multiobj generation should be limited to debug builds in addition to adding debug symbols (which could also happen for release builds). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

The address I receive can't be right because it's in no-man's land part of
x64 address space, at least according to http://en.wikipedia.org/wiki/X86-64 .
At any rate, it segfaults the program.

Looking into it further, this seems to happen with any primitive type, for
example, new double, new uint. Amazingly, though, this code works:
import std.stdio;
void main() {
auto b = (new bool[1]).ptr;
stderr.writeln(b);
*b = 1;
}

Apparently global gets overwritten when the synchronized block is entered in
the following code:
import std.stdio;
void doSynchronized() {
stderr.writeln(In doSynchronized() 1: , cast(void*) global);
synchronized {
stderr.writeln(In doSynchronized() 2: , cast(void*) global);
}
}
__gshared Object global;
void main() {
auto local = new Object;
global = local;
stderr.writeln(In main() 1: ,
cast(void*) global, '\t', cast(void*) local);
doSynchronized();
stderr.writeln(In main() 2: ,
cast(void*) global, '\t', cast(void*) local);
}
Output:
In main() 1: 7F4E605D8E707F4E605D8E70
In doSynchronized() 1: 7F4E605D8E70
In doSynchronized() 2: 0
In main() 2: 07F4E605D8E70
Happens only in 64-bit mode. -O, -inline and -release flags seem to be
irrelevant.
