Patch for mozilla bug 1245076

While testing the clang390-import branch, I ran into issues building Firefox, which manifest as:

/usr/work/share/dim/ports/www/firefox/work/firefox-47.0.1/obj-i386-portbld-freebsd12.0/dist/include/mozilla/mozalloc.h:184:33: error: no type named 'bad_alloc' in namespace 'std'
void* operator new(size_t size) MOZALLOC_THROW_BAD_ALLOC
                                ^~~~~~~~~~~~~~~~~~~~~~~~

Jan Beich already reported this in upstream bug 1269171 [1], and it is caused by the way the Firefox build generates its standard library wrapper headers.

To properly fix this, we need to import the fixes for both upstream bug 1245076 [2] and bug 1269171 [1].  I also had to commit an additional workaround for it in the clang390-import branch, r305496 [3].

Comment 2 Jan Beich freebsd_committer freebsd_triage 2016-09-06 23:53:34 UTC 
Can you confirm Firefox trunk builds fine on projects/clang390-import before r305496? If so I'd prefer to find out what fixed it before using libc++ workaround in base. Maybe you need to add type_traits into config/*-headers like Mozilla bug 1268816 did.

  1. pkg install mercurial
  2. hg clone https://hg.mozilla.org/mozilla-unified/ firefox
  3. hg up central

or if you prefer git

  1. pkg install git
  2. git clone https://github.com/mozilla/gecko-dev/ firefox

  4. cd firefox
  6. ./mach bootstrap # press 2, y, y, 2 in prompts
  7. nice ./mach build
  8. ./mach run

Hand over to dim@ whether to land this one and back out base r305496.

I haven't tried mozilla-central yet, but www/firefox 47.0.1,2 with only patch-bug1268816, and base r305496 reverted, it still dies with:

So I assume we need all three patches, then?  Going to try that next.

Okay, so with all three patches in files/, and base r305496 reverted, www/firefox builds to completion.  Great!

Ah, I was just about to submit a fix for libxul, but nevermind it now. :)  Thanks!
