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.
