Bug 11265 – Segfault while calling instance method of class defined inside struct

Running with D 2.063.2 the following code compiles and runs without any problems. Using git checkout 4a2fabf, the code compiles, but segfaults when trav.empty() is called. Possible changes to the code that will allow it to run correctly are noted in the comments. struct S { //works if the class is moved out of the struct class InnerClass //works if final is added { S s; //works if removed bool empty() { return true; } } } void main() { S.InnerClass trav = new S.InnerClass(); trav.empty(); }

So, just only once initializing of vtbl[] and running semantic on member functions is sufficient. https://github.com/D-Programming-Language/dmd/commit/a95bbf4642e349fffea5a567157a4599ceb96ab9 Merge pull request #2670 from 9rnsr/fix11265 [REG2.064a] Issue 11265 - Segfault while calling instance method of class defined inside struct
