Description Neil Prockter 2005-09-24 07:53:37 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050909 Fedora/1.0.6-1.2.fc4 Firefox/1.0.6

Description of problem:
sed -i segfaults when the target file is in a readonly directory

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. mkdir -p testcases/sed
2. cd testcases/sed
3. mkdir readonly
4. echo hello\\nhello again > readonly/testfile
5. chmod 500 readonly
6. sed -i -e 2d readonly/testfile

Actual Results:  Segmentation fault

Expected Results:  at least
sed: couldn't open temporary file readonly//sedEpzma8: Permission denied
at best use a temp file elsewhere

Additional info:

rhel4 with sed-4.1.2-4 more correctly gives 
sed: couldn't open temporary file readonly//sedEpzma8: Permission denied
(but why not make a tempfile somewhere else in this case)
