Never mind, I got it to fail.

The problem is that the relative path above, which is 200 characters, is 
combined with the path against which it's relative, in this case

D:\bamboo_build_dir\SW-BCB125-VC2008WIN\boost\libs\test\test\

(61 characters), and the Windows limit is 259 characters.

My idea was to automatically use --hash on long paths, but it doesn't seem 
that it would solve much, at least in this specific case. --hash only 
applies to the property portion of the path:

msvc-9\debug\threadapi-win32\threading-multi

so even with it applied, you end up with something like

..\..\..\bin.v2\libs\test\test\user-defined-types-logging-customization-points.test\a3248436d9896874e11a11c8feb7f858\writing-test-ts\user-defined-types-logging-customization-points.obj.rsp

which isn't that far from the limit itself, as much of the length comes not 
from the property list.

Bottom line, either use a shorter BOOST_ROOT, or shorter test names. :-)
