Summary: ClassInfo.interfaces contains null sub-ClassInfos
Product: DGCC aka GDC
Version: 0.24
Platform: PC
OS/Version: Linux
Status: NEW
Keywords: wrong-code
Severity: blocker
Priority: P2
Component: glue layer
AssignedTo: [email protected]
ReportedBy: [email protected]
See the following code:
-----
module test;
interface IConduit : InputStream {
}
interface InputStream {}
void main() {
auto ci = IConduit.classinfo;
// passes:
assert(ci.interfaces.length == 1, "length not 1");
// fails on gdc (but not dmd):
assert(ci.interfaces[0].classinfo !is null, "value is null");
}
-----
Ubuntu 8.10 x86_64, gdc-4.2 from Ubuntu repository (4.2.4 20080705 (prerelease
gdc 0.25 20080312, using dmd 1.024) (Ubuntu 0.25-4.2.4-3.1)).
Both asserts pass on DMD (v1.024 and v1.038), but the second one fails when
compiled using GDC.
This is with Tango installed, in case it matters.
This causes segfaults in Tango's Buffer.share() (via cast(Buffered) ==>
_d_dynamic_cast ==> _d_isbaseof2) :(
