Same testcase as in #270, but with -g or -gc thrown, causes LLVM to crash when it's trying to write debug info.
a.d:
import b;
void main() { C!().f; }
b.d:
template C() {
void f() {
int[1] x;
x[] += x[];
}
}
Compiling just ldc -c -g a.d or ldc -c -gc a.d gives:

Stack dump:
0. Running pass 'X86 AT&T-Style Assembly Printer' on function '@_D1b24_arraySliceSliceAddass_iFAiAiZAi'
The error is from the LLVM trunk but the failure happened also on 2.5.
