Summary: 'glue.c' assertion failure with map(filter)
Product: D
Version: D2
Platform: x86
OS/Version: Windows
Status: NEW
Keywords: rejects-valid
Severity: normal
Priority: P2
Component: DMD

import std.algorithm;
void main() {
int[] a = [1];
map!((int i){ return filter!((int j){ return i; })(a); })(a);
}
With DMD 2.052 gives:
Assertion failure: '!vthis->csym' on line 703 in file 'glue.c'
Equivalent Python 2.6 code:
>>> a = [1]
>>> map(lambda i: filter(lambda j: i, a), a)
[[1]]
