Segfault

Cannot reproduce on current master with mingw and perl-libsass!?

I can confirm this issue exists in 0ae11a4 on OSX with clang.

$ clang -v
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0

Maybe related to #1462 ??

[xzyfer]

Possible. I've left feedback on #1462.

I can confirm after applying #1462 locally the segfault is solved. The following is now produced.

Error: may only compare numbers
        on line 29 of test.scss
>> @if "foo" > 0 {}
