MinGW: ip_tcp test hangs on io_service::run() after tcp::socket::cancel()

[Jim Bell <jim@…>]

The MinGW-32 trunk regression test (current as of 2010/10/21) simply says:

Run [2010-10-21 16:24:46 UTC]: fail

bjam.log says:

300 second time limit exceeded

Running it in gdb verifies that it seems hung indefinitely, and breaking shows this stack trace:

[Richard Webb <richard.webb@…>]

fwiw, I'm not seeing this issue on Mingw 4.5.1 / WinXP (see the RW_Mingw45 runer on Trunk).

[chris_kohlhoff]

I do not think MinGW is the issue here. The VC8 jc-bell.com ip_tcp test also fails. Is this run on the same machine?

If so, I suspect that there is a non-standard (and possibly buggy) Winsock LSP (Layered Service Provider) installed on the system. Perhaps there is a firewall or some VPN software installed?. The Microsoft tool sporder.exe (included with some versions of the Windows SDK) will tell you what LSPs are installed.

[Jim Bell <jim@…>]

Indeed they are run on the same machine. I'll investigate. Thanks for the pointer.
