[Boost-testing] sanity check: -fno-exceptions and regex regression tests

Subject: [Boost-testing] sanity check: -fno-exceptions and regex regression tests

I'm working on packaging a private build of Boost including running
a pass of the regression tests and I'm encountering some problems.
Not being that familiar with bjam or the regression framework, I'd
like to enlist some experienced eyeballs to identify what I'm
missing.

Env:  1.55.0 release, building on Debian squeeze with a gcc-4.6
toolset, 32-bit target.

Problem:  During regex regression tests, the 'regex_regress_noeh'
target is selected and regress/main.cpp gets compiled.  Jamfile.v2
looks like it is turning off exception handling for the target
and '-fno-exceptions' appears in the compilation.  Regression
framework, namely 'test/impl/execution_monitor.ipp', gets included
and clearly issues a throw at line 250.  Compiler reasonably gets
mad at this and errors out failing the regression suite.  (Test
bjam being run with '-a -q' options.)

Q:  What am I missing that I'm failing in the test?  Haven't tried
enabling exceptions for the tests though that's an obvious
workaround as is excluding specific tests.

tnx
