There have been plenty of commits on the trunk in the mean time. And
there was also one crash bug that was resolved at about that time (that
one affected only non-Windows bjam builds, caused by a bug in
Can you reproduce the crash? And find out more precise steps that
cause it? E.g. is it crashing on bjam's build, on internal Boost
Jam/Build tests, or on some concrete Boost library test being run with
it? Is it random? The bug mentioned earlier was random and was caused by
multiple parallel build actions - one creating a temporary file and
deleting it while a the main thread detected the temporary file and then
was missing some error handling when that file could not be found on the
system a moment later.
What exact revision are you reproducing the bug with? Could you try
to manually take a specific Boost Build revision for this?
I see your test site uses Windows XP/SP3 and msvc-9.0/SP1. I'm
running Windows 7 & using msvc-9.0/SP1 for most of the Boost Build/Jam
development here myself and have seen no unexplained crashes on my end
Could you try running the tests once on the same machine without
cross-compiling for Windows Mobile 5.0 and without using stdport? I
doubt any of those have anything to do with the crashes, but it would be
nice to make sure.
If you do not have the time for this, I'd be glad to remote connect
to the system and do some of the research myself, if possible.
Hope this helps.
