This has to be the funniest looking bug I've ever made.
void main(){ (){}; (){}; }
ice.d(1): Error: function has no effect in expression (__dgliteral1)
segfault
Probably the same as bug #3227, it's segfaulting in the same place, and doesn't
segfault on D2.
This smiley variant should compile without errors. But it just segfaults.

Gets into an infinite loop while parsing the mixin.
Here's a superficial patch, which turns it into an ICE with line number.
Doesn't fix the root cause, but still an improvement.
parse.c, line 3358:
while (token.value != TOKrcurly)
{
+ if (token.value==TOKeof) {
+ printf(%s Internal Compiler Error: } expected, not EOF\n,
+ loc.toChars());
+ assert(0);

[Issue 3230] New: std.conv should provide facilities for converting from Roman numerals.

Pretty simple, without further ado here's the patch. Just to be absolutely
clear, I wrote this code snippet entirely by myself and hereby release it into
the public domain.
// Converts a single digit from Roman to arabic.
private uint convertDigit(char digit) pure {
switch(digit) {
case 'I' :
return 1;
case 'V' :
return 5;
case 'X' :
return 10;
case 'L' :
return 50;
case 'C' :
return 100;
case 'D' :
return 500;
case 'M' :
return 1000;
default :
throw new ConvError(
Could not convert Roman digit ~ digit ~ to a number.);
}
assert(0);
}
/**Converts a string containing a Roman numeral to an unsigned integer
* representation.
*
* Throws: ConvError on invalid Roman digit.
*/
uint romanToInt(const char[] roman) pure {
uint result = 0;
uint maxDigit = 0;
for(size_t i = roman.length - 1; i != size_t.max; i--) {
auto romanDigit = roman[i];
uint arabic = convertDigit(romanDigit);
if(arabic maxDigit) {
maxDigit = arabic;
}
// Should we add or subtract?
if(arabic = maxDigit) {
result += arabic;
} else {
result -= arabic;
}
}
return result;
}
unittest {
assert(romanToInt(XIX) == 19);
assert(romanToInt(DCLXVI) == 666);
assert(romanToInt(XXX) == 30);
assert(romanToInt(MDCCCLXXXVIII) == 1888);
assert(romanToInt(XCIX) == 99);
assert(romanToInt(XLIX) == 49);
assert(romanToInt(IV) == 4);
assert(romanToInt(XLV) == 45);

Strangely, the compiler's behavior differs based on the type of the result of
get(). While the workaround works in this instance (returning Object), it
doesn't seem to work for any other type. For instance, given this struct:
struct Proxy
{
int get() { return 0; }
alias get this;
}
If you do:
Proxy p;
int x = p;
you get an error saying it can't convert type Proxy to int. But here's the
real kicker:
Object x = p;
_Now_ the compiler says that it can't convert p.get() of type int to Object!
So for some reason, it's using the alias this when it shouldn't, and not using
it when it should.
