Summary of Problem
Compilation fails with an internal compiler error.
Steps to Reproduce
Source Code:
proc merge(xs: [?Dom] ?eltType, ys: []) {
const count = xs.size + ys.size;
var dst: [0..#count] eltType;
if (xs.size == 0) { dst = ys; return dst; }
if (ys.size == 0) { dst = xs; return dst; }
var i_xs = 0;
var i_ys = 0;
var i = 0;
var writeFromFirst = lambda() {
dst[i] = xs[i_xs];
i_xs += 1;
i += 1;
};
var writeFromSecond = lambda() {
dst[i] = ys[i_ys];
i_ys += 1;
i += 1;
};
while (i < count) {
if (xs[i_xs] <= ys[i_ys]) { writeFromFirst(); }
else { writeFromSecond(); }
}
return dst;
}
proc main()
{
var x = merge([1, 7, 8], [5, 11]);
}
p.s. don't mind the code itself, it's incorrect. This shouldn't cause the compiler to crash though.
