[Boost-testing] [asio] [test] CVS head: Out Of Memory Results in Endless Loop

Platform: Solaris x86, gcc 4.2.0, Boost CVS HEAD

I'm running the Boost Regression tests on a machine at home and
several of the asio test programs appear to be eating up all physical
memory and hitting std::bad_alloc.

The out-of-memory condition seems to be getting swallowed up by
Boost.Test, resulting in endless loops of this (according to truss):

lwp_sigmask(SIG_SETMASK, 0x00000400, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
setcontext(0x08046A70)
    Incurred fault #6, FLTBOUNDS  %pc = 0xD2792661
      siginfo: SIGSEGV SEGV_MAPERR addr=0xA4AF5444
    Received signal #11, SIGSEGV [caught]
      siginfo: SIGSEGV SEGV_MAPERR addr=0xA4AF5444
lwp_sigmask(SIG_SETMASK, 0x00000400, 0x00000000) = 0xFFBFFEFF [0x0000FFFF]
setcontext(0x08046A70)
    Incurred fault #6, FLTBOUNDS  %pc = 0xD2792661
      siginfo: SIGSEGV SEGV_MAPERR addr=0xA4AF5444
    Received signal #11, SIGSEGV [caught]
      siginfo: SIGSEGV SEGV_MAPERR addr=0xA4AF5444

When I run one of these test programs under the debugger, here's the
stack trace when gdb first detects the OOM:

I think this is a problem in both the asio test programs for using too
much memory, and in Boost.Test swallowing the error and going into an
infinite loop.
