Bug 1072 – CTFE: crash on for loop with blank increment

static char[] hello() { char[] result=""; for(;;) result ~= `abc`; return result; } void main() { pragma(msg,hello()); } this code should also make ur computer DoS, but DMD AV

Added to DStress as http://dstress.kuehne.cn/compile/a/array_initialization_33_A.d http://dstress.kuehne.cn/compile/a/array_initialization_33_B.d http://dstress.kuehne.cn/compile/a/array_initialization_33_C.d http://dstress.kuehne.cn/compile/a/array_initialization_33_D.d http://dstress.kuehne.cn/compile/a/array_initialization_33_E.d

this code won't make dmd access violation: static char[] hello() { char[] result=""; int i; for(;;i++) result ~= `abc`; return result; } void main() { pragma(msg,hello()); } the problem is intepret.c line 594, it assumes increment is an object which is never null, while in this case, the loop doesn't have any increment statement. So a quick fix is add to line 594 if (!increment) continue;

added keywords. Walter probably missed this one because the bug title is terrible!

So make it less terrible.

haha, you guys are right.
