That is interesting. The regression command line I run is:

python regression.py --v2 --tag=RC_1_34_0 \
--toolsets=msvc-8.0express,msvc-7.1,borland,gcc  --user=anthonyw \
--force-update --runner=JustSoftwareSolutions-V2 \
--bjam-options="release -l600"

The bjam.log for that test says:

gcc.compile.c++ g:\boost\rc-1-34\results\boost\bin.v2\libs\statechart\test\Trans
itionTestNormal.test\gcc-mingw-3.4.0\release\TransitionTest.o

So the compile just failed for some reason.

When I run just that test directly using the following command line, it
passes.

bjam --v2 release gcc TransitionTestNormal -l600

Bizarre. Anyone got any ideas?

Actually, I just checked, and at one point during the run, my machine ran out
of pagefile space. You'd have thought that 1Gb RAM and 2Gb page file would be
enough, but maybe not. I don't see why things would then run fine on their
own, though --- unless bjam requires so much memory for the dependency chart
for all the targets when run in one great big clod that there's no memory left
for the compiler.

I'll increase the page file to 3Gb for the next run.
