The patch is not ready for prime time because I have been unable to test
it. When I install the patch, mintty hangs on startup without showing
the bash prompt, and a grep process is left running. I can kill the
grep process through the Windows Task Manager and then get a bash
prompt, but every command I try to run hangs and has to be killed
through the Task Manager. In particular, I can't run the test cases
that I sent in the above report.
So either there's something wrong with the patch or else it triggers a
bug somewhere else. I don't know how to debug this.
Takashi, do you think this could be related to the signal issues that
you've been working on? The patch potentially eliminates some SIGBUS
signals that were raised incorrectly before, and it also potentially
causes some (correct) SIGBUS signals that were not raised before.
I tried applying my patch on top of cygwin 3.5.4, and the behavior is
the same. So it doesn't seem to be related to the recent signal issues.
