Issue ID: 18305
Summary: SysTime crashes ctfe
Product: D
Version: D2
Hardware: x86_64
OS: Linux
Status: NEW
Severity: enhancement
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
Steps to reproduce:
void main() { mixin({ return (SysTime.init is SysTime.init) ? "" : ""; }()); }
Expected:
nothing happens
Outcome:
Compiler crashes.
Observation:
I added some logging, and
test.d(5) BinExp::interpretCompareCommon() SysTime(0L, Rebindable(null, )) is
SysTime(0L, Rebindable(null, ))
ctfeIdentity op = 'TOKidentity', e1 = SysTime(0L, Rebindable(null, void)), e2 =
SysTime(0L, Rebindable(null, void))
test.d(5): Error: CTFE internal error: bad compare of void and void
core.exception.AssertError@ddmd/ctfeexpr.d(1345): Assertion failure
It looks like the second field in RebindableCommon's union ends up
void-initialized, and CTFE can't figure out how to compare that.
