0.6.3 broken on MacBookAir4,2?

[Grant Pannell]

Hi,

Just upgraded to 0.6.3, but I can't get it to work on my MacBookAir4,2. After running install.sh and rebooting, I get stuck on a grey screen. Have to hold option and boot to recovery and wipe out the EFI folder.

0.6.2 seemed to work fine, so I'm not entirely sure what's going wrong? I guess I'm also a little lost as to how I'd even go about troubleshooting it?

I run a triple boot, ML, Windows 8, Ubuntu 12.10. Diskutil reports something like this:

0 GUID_partition_scheme,,251.0 GB, disk0
1 EFI,,209.7 MB, disk0s1
2 Apple_HFS, Macintosh HD, 35.0 GB, disk0s2
3 Apple_Boot, Recovery HD, 650.0 MB, disk0s3
4 Microsoft Basic Data, Windows HD, 200.0 GB, disk04
5 Microsoft Basic Data,, 15.2GB, disk0s5

Any way to troubleshoot this?

I also rolled back to 0.6.2 and everything works perfect.

I've tested several ways on my own 32-bit Mac Mini and I've been unable to reproduce this problem. Therefore, I'll need some help in tracking it down. If you (or somebody else with this problem) would be willing to experiment a bit, I'd appreciate it. The first thing is to isolate the problem to the install.sh script or to the rEFInd binary:

1. Try installing rEFInd 0.6.2 with the install.sh script from 0.6.3. See if it works.
2. Try installing rEFInd 0.6.3 with the install.sh script from 0.6.2. See if it works.

Thanks.

1. Try installing rEFInd 0.6.2 with the install.sh script from 0.6.3.

Works.

1. Try installing rEFInd 0.6.3 with the install.sh script from 0.6.2.

Does not work.

OK, so it's in the binary. I've reviewed the code, and I may have found the problem. Here's a test fix:

The source is in the git repository, if you care about that. Could you please try that and tell me if it works? Thanks.

Still gives me a grey screen :(

If it helps, I setup a build environment, rolled back some changes from 0.6.3 to 0.6.2 and found this portion in config.c is causing the problem:

   if (SelfVolume->VolName) {
      SelfPath = StrDuplicate(SelfVolume->VolName);
   } else {
      SelfPath = AllocateZeroPool(256 * sizeof(CHAR16));
      SPrint(SelfPath, 255, L"fs%d", SelfVolume->VolNumber);
   } // if/else
   MergeStrings(&SelfPath, SelfDirPath, L':');
   GlobalConfig.DontScanDirs = SelfPath;

[Grant Pannell]

And more specifically, on my system, the line that causes a crash is:

SelfPath = StrDuplicate(SelfVolume->VolName);

Edit: Actually, I'm not sure if that line specifically causes the crash, but if it's commented out, everything works fine. I have no idea how I can debug these things to determine whether that line crashes or if it affects something elsewhere which then crashes.

I've fixed this; it's now available as rEFInd 0.6.4.

[Grant Pannell]

Thanks, 0.6.4 works great.
