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

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]]

Any chance it is the same as issue 4129?

Reduced test case (I think):
----------------------------------
void x(alias pred)() {
pred();
}
void main() {
x!((){
int i; // declare in outer scope
x!((){
cast(void) i; // access in inner scope
});
});
}

(In reply to comment #4)
Compiles and runs with 2.059 Win32
Yes, both cases now compile. But I have found a way to trigger the same error.
First module, named "module1.d":
import std.stdio;
import module2;
void main() {}
Second module, named "module2.d":
import std.algorithm: reduce;
struct Foo {
string bar() {
auto spam = (string s, int) => "";
return reduce!spam("", [1]);
}
}
It generates, dmd 2.061alpha:
Assertion failure: '!vthis->csym' on line 787 in file 'glue.c'
Since you say this used to work before, it's now a regression.

Sorry, I guess it's a different bug, so I close this down and open another one.
So ignore comment 6 please.
