20050208 hyperthreading bug is back ?
Summary: I reported before that the 20050206 snapshot appeared to fix the hyperthreading bug for me. Now it seems that the next snapshot 20050208 broke it again. Test Case: -- Command: find z | while read f; do chown username $f; done; and a longer version of the test case command, (same results): export i=1; find z | while read f; do printf %8i: %s\n $i $f; \ chown username $f; ((i++)); done; Note: z is a directory tree under /cygdrive/c with 4000 odd files in it. Result: --- after 700 to 1000 files bash hangs with the following error message: 2 [exiting thread] bash 3328 cygthread::stub: erroneous thread activation, name is NULL The first number varies (2, 4, 8) as well as the number after bash which I take it is the pid. NOTE: The error only occurs when I run this from the command prompt. I put the same command in a file (preceded by a #!/bin/bash -line) and called it chownz.bash ./chownz.bash completes as expected . ./chownz.bash also completes as expected The same test runs without problems on the 20050206 snapshot. My system: -- HP Pavilion, P4HT3.2G, 1G memory, 200G SCSI HD $ uname -a CYGWIN_NT-5.1 nodename 1.5.13s(0.118/4/2) 20050208 14:21:58 i686 unknown unknown Cygwin I tried to include the output from 'cygcheck -s -v -r | tee cygcheck.out' but the interface will not accept lines longer than 80 chars. I can mail it across, just let me know.

None of my simple test cases seems to fail, but in the guts of a 2-hour build, I get that error message and things grind to a halt. -Rolf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

OK, but then it would perhaps be interesting to know if the 20050206 snapshot works for you there - or, in case it fails, whether the error is the same or different ?

How wonderfully bittersweet that I can now reproduce these problems at will. :-) I have a patch that makes it better but a long running test died while I was in the middle of typing this, so apparently it isn't perfect. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
