Package: less Version: 406-0 Severity: normal I have managed to crash less! I have reduced the crash to this test case:
$ echo $LINES $COLUMNS
30 239
$ echo hello > test
$ echo goodbye > test2
$ chmod -r test2
$ less test test2
<now press :n and watch it crash>
It seems that when less views a file which does not fill the entire window,
followed by pressing ":n" to go to the next file (for which I have no read
permission) it segfaults.
The following is the end of an ltrace immediately before the crash:
open("test2", 0, 041) = -1
__errno_location() = 0x2b851ec26aa8
strerror(13) = "Permission denied"
strlen("Permission denied") = 17
strlen("test2") = 3
calloc(23, 1) = 0x627930
snprintf("\001\200\255\373\377\177",
4297040, "\377\377\377\377\377\377\377\377"...) = 22
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
The strace was uninteresting, as was the gdb backtrace.
Hope that's of some use,
Bruce
