http://d.puremagic.com/issues/show_bug.cgi?id=1573 Summary: ICE when using -O flag and static if's Product: DGCC aka GDC Version: 0.24 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: glue layer AssignedTo: dvdfrdmn users.sf.net ReportedBy: jeffd gwava.com I made some performance changes by adding a static if to a hash keyCompare function to deal with null.opEquals issues: private bool _keyCompare(T first, T second) { static if (is(T : Object)) return cast(bool)(first ? first == second : second is null); return cast(bool)(second == first); } While testing, I was able to compile fine (with -O, etc), however, linking in a Config module that uses the Hash template in several places, I get: tetra/util/container/Hash.d: In member function ‘_keyCompare’: tetra/util/container/Hash.d:215: internal compiler error: in emit_move_insn, at expr.c:3162 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. For Debian GNU/Linux specific bug reporting instructions, see <URL:file:///usr/share/doc/gcc-4.1/README.Bugs>. Line 215.d of Hash.d is the declaration of the _keyCompare function. That's with compiling with -O -release. Removing the -O it compiles and runs as expected. Changing the line: return cast(bool)(second == first); to just return false; also allows compilation without error (but doesn't run as expected, obviously). --

http://d.puremagic.com/issues/show_bug.cgi?id=1573 Little update, changing the _keyCompare function to the following removes the ICE: private bool _keyCompare(T first, T second) { static if (is(T : Object)) return cast(bool)(first ? first == second : second is null); if (first == second) return true; return false; } --

Can you post a self-contained example or a URL to get the full source? You may also want to try a newer Debian package if one is available. --

http://d.puremagic.com/issues/show_bug.cgi?id=1573 I've tried the latest .deb, exact same error. I would have to package up stuff from our commercial source to give to you to replicate the issue, as with smaller test cases, there is no compiler issue. Unfortunately, I'm not sure if I can get permission to give you one of the required components. The Hash component wouldn't be an issue however. I'll try and make something that replicates the issue without using the component that I can't give and post it here. --
