Hi, 

it seems that 

commit c0d2d29284389a1e7f924583ff6bd59128b9436b

    -- is required before extra test module arguments

has at least broken my Boost.Build driven tests, as I now get:

Usage: my_test-clang38 [Boost.Test argument]... -- [custom test module 
argument]...

For detailed help on Boost.Test parameters use:
  my_test-clang38 --help
or
  my_test-clang38 --help=<parameter name>

for every test which has extra command line arguments. I strongly suspect this 
breaks some libraries in Boost itself which e.g. need to read some input 
files.

Right now I'm lost at how to fix this in Boost.Build's testing.jam as it seems 
we somehow have to specify different arg sets. And how to get "--" into the 
commandline at all.

And in the light of the ongoing c++11/03 discussion it would have been nice to 
issue a warning before commiting breaking and/or behavioural changes.

Any ideas?

Yours,

Jürgen
