[Boost-users] SEGV in argv_traverser::handle_mismatch() on arg with leading space

argv_traverser::handle_mismatch() appears to barf when parsing argv[1]
with leading (or only) spaces.

The examples boost/libs/test/example/external_main_example_1.cpp gets
a SEGV in include/boost/test/utils/runtime/cla/argv_traverser.ipp at
  m_remainder[m_remainder_size++] = p_separator

gdb says
p m_remainder_size
$1 = 116625

I tried with test_case_template_example.cpp but got linker errors
consistent with a missing main. That example's include didn't include
the path segment "included/" so I thought it should compile with a
-DOOST_TEST_DYN_LINK -lboost_unit_test_framework . Anyways, the first
example should be enough to track down the bug.
