Test case: ---------------------------------------- struct S { void opAssign(in int other) pure { } } void add() pure { S[int] d; d[0] = 1; } ---------------------------------------- x.d(7): Error: variable __aatmp3 forward referenced x.d(7): Error: pure nested function 'add' cannot access mutable data '__aatmp3' x.d(7): Error: variable __aatmp3 forward referenced x.d(7): Error: pure nested function 'add' cannot access mutable data '__aatmp3' x.d(7): Error: variable __aatmp3 forward referenced x.d(7): Error: pure nested function 'add' cannot access mutable data '__aatmp3' ---------------------------------------- The bug is introduced somewhere between 2.048 and 2.052.

The bug was introduced in commit 44d7881 (fix bug 2451), manifesting itself as a Segfault (null pointer dereferencing). The Segfault was later converted to an error in commit 37aacfc (bug 5131). https://github.com/D-Programming-Language/dmd/commit/44d7881 https://github.com/D-Programming-Language/dmd/commit/37aacfc
