Bug 11376 – ICE on __traits(compiles, ...) with invalid array-op

//arrayTest.d template I(T ...) { alias I = T; } auto sumArrs(T0, T1)(T0[] a, T1[] b) { a[] += b[]; //no ICE without this line return a; } pragma(msg, __traits(compiles, sumArrs(I!(string[], string).init))); $dmd arrayTest.d false Statement::toCBuffer() Internal error: s2ir.c 135 This is a very heavy reduced test-case from a much larger program. The original __traits(compiles, ...) was in a static if, not a pragma(msg, ...)
