calling render with null data results in 'malloc pointer being freed was not allocated'

[DinisCruz]

here is the test that replicates the issue

describe 'test-SCSS_Compiler',->

  it 'throws malloc error', (done)->
    sass = require('node-sass');
    options =
      data: null,
      outputStyle: 'compressed',
      success: done
    sass.render options

  return

which results in

node ./node_modules/mocha/bin/mocha --compilers coffee:coffee-script/register --recursive -R list tests


  1) test-SCSS_Compiler throws malloc errpr
node(9602,0x7fff7c770300) malloc: *** error for object 0x103c88e44: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

Hello,

Well, it appears to be a trivial edge case.

Perhaps @mgreter might be able to take a look OR this is already fixed with new libsass API (which we are at the verge of finalizing the implementation: #543).

Nonetheless, we will take a look.

Thanks!

v2.0.0-beta is just released. Please test if you can reproduce this issue.

[DinisCruz]

ok I will try it (tracking this action here TeamMentor/TM_4_0_Design#179)

Lets track this issue at sass/libsass#776.

This also occurs if data is a buffer which—it would seem—hasn't always been the case.
