[Insight-users] Problem with LandmarkWarping2.cxx in ITK-4.4.0?

[Bradley Lowekamp]

Hello,

I am just curious if it's a compiler issue or one with the code.

It's been a while since there has been a bonified version of GNU GCC with Xcode. I am running OS 10.8.5, check this out:

$ /usr/bin/gcc -v
Using built-in specs.
Target: i686-apple-darwin11
Configured with: /private/var/tmp/llvmgcc42/llvmgcc42-2336.11~182/src/configure --disable-checking --enable-werror --prefix=/Applications/Xcode.app/Contents/Developer/usr/llvm-gcc-4.2 --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-prefix=llvm- --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/ --with-slibdir=/usr/lib --build=i686-apple-darwin11 --enable-llvm=/private/var/tmp/llvmgcc42/llvmgcc42-2336.11~182/dst-llvmCore/Developer/usr/local --program-prefix=i686-apple-darwin11- --host=x86_64-apple-darwin11 --target=i686-apple-darwin11 --with-gxx-include-dir=/usr/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

That is llvm masquerading as gcc.

There is also clang as an option. I'd give that a try. Upgrading to Macericks is going to another set of problems. 

Check out the information here:

This may be a good opportunity to run git-bisect, if the issue can be reproduced.

The moving image was roughly in the correct spot of the first landmark, but was at a completely incorrect scale. I reverted to 4.3.2 and had no issues at all. I'm fine using 4.3.2, but thought I would mention it here in case anyone has a solution or pointer.
