BTW, Martin, do you have any plan in packaging a GNU Radio 2.6 release
for Windows on CDROM ? I can help you if need be. Are there any
other volunteers for this task lurking on the list? Any beta-testers?
What about the Knoppix CDROM and GNU Radio 2.6 ?

Actually, you should have run the "make check" first, which
should have caught the problem. Maybe you did already?

The fact under Windows is the virtual memory circular buffer (vmcircbuf)
is not as reliable as under Linux and other *nix-like systems.
The gr_vmcircbuf_mmap_createfilemapping method heuristically
trys to map a file area twice, hopping both mapping will be contiguous.
The few retrys may not get through sometimes. It's nasty.
Can you please try to run several times the test_vmcircbuf.exe program
and see if it always fails?

What version of Windows are you running ? What CPU ? How much memory?
