It seems I need your /etc/ld.so.cache :-) ...I'm not able to reproduce this problem (as well as bug #1403971). Can you try it with more(1) from Fedora? The problem with "repeat search crash" should be already fixed on Fedora by upstream commit https://github.com/karelzak/util-linux/commit/bc1ed338814f69473629b04c5e9efae5d7db3b72 It just needs a file that does not match. I used /etc/ld.so.cache as an example, based on user example on rhbz#1403971 :) I confirm it is corrected in Fedora 25. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2017:2186 |
While trying to figure a reproducer to rhbz#1403971 I managed to get /usr/bin/more to crash on another condition. For example: (gdb) bt #0 __strlen_sse2 () at ../sysdeps/x86_64/strlen.S:31 #1 0x00007ffff78c8d0f in __regcomp (preg=preg@entry=0x7fffffffde30, pattern=0x0, cflags=cflags@entry=8) at regcomp.c:499 #2 0x0000000000405813 in search (buf=<optimized out>, file=file@entry=0x60ee00, n=n@entry=1) at text-utils/more.c:1591 #3 0x0000000000405d6a in command (filename=filename@entry=0x0, f=f@entry=0x60ee00) at text-utils/more.c:1344 #4 0x0000000000406664 in screen (f=f@entry=0x60ee00, num_lines=<optimized out>, num_lines@entry=32) at text-utils/more.c:708 #5 0x0000000000402365 in main (argc=<optimized out>, argv=<optimized out>) at text-utils/more.c:503 Sample steps to reproduce: $ /usr/bin/more /etc/ld.so.cache Press //.a to search for a pattern. Press <Enter> Press . to repeat least search. It crashes.
