Segmentation Fault on startup - RH Fedora 2

[hexhead]

I get this error after using tune2fs to get around the directory index problems of ext3 filesystems mentioned in the knowledge base.

Running Fedora 2 on Dell Pecision 670, dual 3GHz Xeons, 2GB RAM:

bwhite@localhost:~$ /usr/local/lv71/labview

LabVIEW caught fatal signal
7.1 - Received SIGSEGV
Reason: unknown
Attempt to reference address: 0x0
Segmentation fault

Are you installing LabVIEW on a freshly formatted computer? Does this computer have any previous versions of LabVIEW installed? Did the installation give any error messages?

This is a fresh installation on a new computer. No previous NI software exists. The install from RPMS went well with no errors. When I first started labview, I received an error that I "fixed" with tune2fs to turn off the funky ext3 filesystem indexing concerning "." and ".." directory index entries. After that I get this new "unknown" error addressing 0x0.

Hm, this is a new instance of this error. Do you have Fedora Core 1? I know our previous issues with this seg fault was different based on if Fedora Core 2 was installed fresh or installed after Fedore Core 1 had already been installed. The funky ext3 filesystem indexing (fixed with tune2fs) was needed only if installing Fedora Core 2 fresh. Upgrading from Fedora Core 1 with Core 2 did not exhibit any problems.

I will go ahead and submit a report to reproduce this issue. In the meantime, try installing Fedora Core 1 and then upgrading to Core 2 to see if that helps.

Thanks!

check the file permissions on /tmp

All users should have read, write, and execute permissions (chmod 777)
set for the /tmp directory.

You'll get a sig fault if LV cannot write to that directory. Reply back
if it works.

I'm not keen on the idea of (re)installing two OS's; it took a few days to get one setup, and I don't relish the thought of going through that again. Would uninstall/reinstall of LabView make any difference since I made the tune2fs change?

[hexhead]

This is the permissions on /tmp:

[bwhite@ansel GSSDA]$ ls -ld /tmp
drwxrwxrwt 11 root root 57344 Sep 29 11:04 /tmp

[hexhead]

After uninstall/reinstall:

[bwhite@ansel paper]$ /usr/local/bin/labview

LabVIEW caught fatal signal
7.1 - Received SIGSEGV
Reason: address not mapped to object
Attempt to reference address: 0x27e7110c
Segmentation fault

Attached are the failure logs if that helps.

Oh well. It was worth a try.
