<pre>Working on Linux (Ubuntu 4.10) and gdc 4.10.0 20140629 I get an ICE with the
following backtrace when compiling with both -g and -O1 (either one works fine
but not both).
code:
import std.process;
import std.string;
string runSomething() {
return execute("some executable").output.chomp;
}
void main() {}
cmdline: gdc -g -O1 ./test.d -o/tmp/test
backtrace:
