G++ was fixed to reject this, the code is invalid.

These should be qualifying the type as std::ptrdiff_t.

That's another bug I fixed yesterday:

Looks like the same issue as brainparty and isgtk.

The root cause is using ptrdiff_t not std::ptrdiff_t again.

I thought that might be my fault so looked into it, but it's an
upstream bug in SuperCollider, fixed in the latest release. It only
used to work with GCC 4.8 because our std::map was non-conforming in
exactly the right way for supercollider's non-conforming allocator to
do the right thing.

The sslsniff and tripwire failures are the same issue, G++ no longer
allows this:

try {
} catch (int var) {
  int var;

So several cases are real bugs that G++ now catches, and some were
known libstdc++ regressions that were fixed yesterday.
