http://d.puremagic.com/issues/show_bug.cgi?id=5079 P.S. The ICE naturally also affects __traits(compiles, T[0].sizeof ), which make escaping the underlying bugs very difficult. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

http://d.puremagic.com/issues/show_bug.cgi?id=5079 Having just debugged/patched/filed Issue 5155, I've found that A) that this test case is a different error and B) they both result from trying to calling toIR on a statement containing an expression with an __error type (current ty == 37). In the case of 5155, while debugging I found that detecting the erroneous ReturnStatement inside the CompoundStatement and eliding it produced the correct error message (though this might have been as much luck, as anything else). Looking at the source code, although if(exp) gets tested a fair amount, if(exp->type->ty == terror) never does, so I'm assuming that the code that checks for __error inside expressions lives elsewhere.
