$ cat gdcbug.d
class ArsdExceptionBase : object.Exception {
this(string operation, string file = __FILE__, size_t line = __LINE__,
Throwable next = null) {
super(operation, file, line, next);
}
}
template ArsdException(alias Type, DataTuple...) {
static if(DataTuple.length)
alias Parent = ArsdException!(Type, DataTuple[0 .. $-1]);
else
alias Parent = ArsdExceptionBase;
class ArsdException : Parent {
DataTuple data;
this(DataTuple data, string file = __FILE__, size_t line =
__LINE__) {
this.data = data;
static if(is(Parent == ArsdExceptionBase))
super(null, file, line);
else
super(data[0 .. $-1], file, line);
}
static opCall(R...)(R r, string file = __FILE__, size_t line =
__LINE__) {
return new ArsdException!(Type, DataTuple, R)(r, file,
line);
}
}
}
Iain Buclaw notes the bug seems specific to 12.x, as the reproduction code
works well on gcc 13 and mainline.
/// This example shows how you can throw and catch the ad-hoc exception types.
void main() {
// 0 or 1 args works
try {
throw ArsdException!"Test"(1);
} catch(ArsdException!"Test" e) { // catch it without them
}
// 2 or more args causes ice
try {
throw ArsdException!"Test"(4, "four");
} catch(ArsdException!("Test", int, string) e) { // catch it and use
info by specifying types
assert(e.data[0] == 4); // and extract arguments like this
assert(e.data[1] == "four");
}
}

d: Add test case for PR110959.
This ICE is specific to the D front-end language version in GDC 12,
however a test has been added to mainline to catch the unlikely event of
a regression.
