Building the following code with DMD 2.059head fails in ICE. MESSAGE: Assertion failure: '0' on line 277 in file 'tocsym.c' DMD2.058 works. ------------------------------------ struct File { ~this(){} } struct ByLine { File file; // foreach interface @property bool empty() const { return true; } @property char[] front() { return null; } void popFront(){} } void main() { int dummy; ByLine f; foreach (l; f) { scope(failure) // 'failure' or 'success' fails, but 'exit' works dummy = -1; dummy = 0; } }
