Uninstalling, cleaning, and then re-installing clang-3.6 results in the same error:

What’s the output of:

Try cleaning clang-3.6 and installing again. If it fails, could you post the output of this:

$ CLANG_SRC=$(port work clang-3.6)/trunk
$ $(CLANG_SRC)/Release+Debug+Asserts/bin/clang \
        -arch x86_64 -c -integrated-as \
        $(CLANG_SRC)/projects/compiler-rt/make/platform/clang_darwin_test_input.c \
        -isysroot $(xcrun --sdk macosx --show-sdk-path) -o /dev/null
$ echo $?

[mopihopi]

Cleaning and installing again still fails. The output of the above commands (changing $(CLANG_SRC) to ${CLANG_SRC}):

$ CLANG_SRC=$(port work clang-3.6)/trunk
$ ${CLANG_SRC}/Release+Debug+Asserts/bin/clang -arch x86_64 -c -integrated-as ${CLANG_SRC}/projects/compiler-rt/make/platform/clang_darwin_test_input.c -isysroot $(xcrun --sdk macosx --show-sdk-path) -o /dev/null

Looks like heap corruption to me.

3rd party (upstream) to fix. Hopefully a newer svn revision will fix the issue for you. I'll update it next week some time. You might want to file a ticket at ​http://www.llvm.org/bugs with the information from your previous comment.

[mopihopi]

Thanks. I changed the svn.revision from 224827 to 225216 in the Portfile, rebuilt llvm-3.6 and clang-3.6, and am no longer seeing the issue.

[jeremyhu (Jeremy Huddleston Sequoia)]

Great news. I'll make that change.
