Description David Tonhofer 2002-05-31 12:43:09 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

Description of problem:
'less' segmentation faults under linux rescue mode (even w/o any
arguments). This is probably less an error about 'less' than about the
rescue mode

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

How reproducible:

Steps to Reproduce:
1. Start linux rescue mode from CD
2. In the tty1 shell, type
3. less

Actual Results:  Segmentation fault

Expected Results:  File contents should show up

Additional info:

'less' segmentation faults under linux rescue mode (even w/o any
arguments) Here is some information from strace and the debugger.
More can be delivered on request.

The last messages from strace before the fault:

strace:  close(3)       = 0
         brk(0)         = 0x805efb4
         brk(0x805efe4) = 0x805efe4
         brk(0x805f000) = 0x805f000

GDB says:

SIGSEGV in 0x0805a002 in _IO_stdin_used()
           0x08048e5a in _init()
           0x400690af in __libc_start_main()from /lib/libc.so.6

instructions: 0x805a000 jae 0x805a06a <_IO_stdin_used+13222>
              0x805a002 gs 
              0x805a003 insb (%dx),%es:(%edi)

This is probably not going to help much, so as I said -- ask
for more info if you want to.

doesn't seem to be a problem in less. changed component to anaconda
Comment 2 Michael Fulbright 2002-06-04 10:36:05 EDT
I haven't had this problem - if you look on VC3 and VC4 do you see any read
errors? If you were running rescue mode from a CD I would hazard to guess the CD
is bad.
Comment 3 Michael Fulbright 2002-07-15 12:53:45 EDT
Closing due to inactivty, please reopen if you have additional information to add.
