I'm quite surprised to find that this problem still exists in the current trunk
for platforms without TLS (i.e. many embedded platforms). Although I don't see
a recursive call but a rather more direct chain of events:
1) We completely run out of heap memory calling operator new. To see this
problem, less than the size of 'struct __cxa_eh_globals' must be available.
2) new throws std::bad_alloc, causing __cxa_allocate_exception to be called
3) __cxa_allocate_exception calls malloc() which still fails, but an emergency
buffer is available, so it is able to continue.
4) But __cxa_allocate_exception then calls __cxa_get_globals()
5) If __cxa_get_globals() has not been called before, it will allocate the
globals structure beginning with a call to malloc()
6) malloc() still fails, so std::terminate() is called.
The effect is that if std::bad_alloc is the first C++ exception this thread has
thrown, we can never catch it - instead the program is always abruptly
terminated, by default with abort(). This seems to be a surprisingly serious
issue given this is a 7 year old bug report.

The issue seems more tricky, even for TLS platforms, see:

If my analysis is correct, this PR is still valid *only* for targets not
defining _GLIBCXX_HAVE_TLS. Otherwise, fixed by:

Ah! Now I see, it's because of Benjamin and Ulrich recent changes, involving
thread local storage. Therefore my amended testcase proposal should be fine on
platforms not defining _GLIBCXX_HAVE_TLS. We should check that.

Puzzling testcase...
Humm, strange. The new testcase *passes*... Still, the original analysis makes
a lot of sense to me (like Howard's suggestion for a fix). But we badly need a
testcase! Any idea?

... possibly using a "real" memory allocation, touching all the involved pages.

Sorry. Actually the testcase is not correct stand-alone, fails at line 13. I'm
currently checking whether is correct when the testsuite support (memory
limits) is present.

Trivial testcase
Hi. I'm attaching a trivial testcase (*). In fact, I consider this bug pretty
serious! Howard, any chance you can show your patch to Geoff or post it to the
mailing list(s) for a review?
(*) Of course, it reliably fails stand-alone, without the def-out bits, only on
32-bit machines equipped with less than ~ 1G.
