[Konsole-devel] Bug#45855: konsole leaks memory on a simple keypress

[claviola at debian.org]

Package: konsole
Version: 1.1.2 (using KDE 3.0.2 )
Severity: crash
Installed from:     (3.0)
Compiler:          gcc version 2.95.4 20011002 (Debian prerelease)
OS:                Linux (i686) release 2.4.18
OS/Compiler notes: 

Hello,

I've found out that konsole will practically bring my system down by sucking all the RAM it can until the kernel goes out of memory and kills the bash instances. It happens when you press RET while holding down the Shift key. It seems to me that when I do that, it runs across my entire bash history and tries to execute everything at once (!). I'm posting the relevant parts of an strace below:

7601  stat64("/home/claviola/.bash_history", {st_mode=S_IFREG|0600, st_size=7697, ...}) = 0
7601  open("/home/claviola/.bash_history", O_WRONLY|O_APPEND|O_LARGEFILE) = 3
7601  write(3, "test\n", 5)             = 5
7601  close(3)                          = 0
7601  open("/home/claviola/.bash_history", O_RDONLY|O_LARGEFILE) = 3
7601  fstat64(3, {st_mode=S_IFREG|0600, st_size=7702, ...}) = 0
7601  read(3, "mv .mozilla/ .netscape\nscr-bx\nps"..., 7702) = 7702
7601  close(3)                          = 0
7601  open("/home/claviola/.bash_history", O_WRONLY|O_TRUNC|O_LARGEFILE) = 3
7601  write(3, "scr-bx\nps xa\nps xa|grep kon\nps x"..., 7679) = 7679
7601  close(3)                          = 0
7601  rt_sigprocmask(SIG_BLOCK, [CHLD TSTP TTIN TTOU], [HUP INT ILL TRAP ABRT BUS FPE USR1 SEGV USR2 PIPE ALRM TERM XCPU XFSZ VTALRM SYS RTMIN], 8) = 0
7601  ioctl(255, 0x5410, [7601])        = 0
7601  rt_sigprocmask(SIG_SETMASK, [HUP INT ILL TRAP ABRT BUS FPE USR1 SEGV USR2 PIPE ALRM TERM XCPU XFSZ VTALRM SYS RTMIN], NULL, 8) = 0
7601  setpgid(0, 7601)                  = -1 EPERM (Operation not permitted)
7601  rt_sigaction(SIGHUP, {SIG_DFL}, {0x80807c0, [HUP INT ILL TRAP ABRT BUS FPE USR1 SEGV USR2 PIPE ALRM TERM XCPU XFSZ VTALRM SYS], 0x4000000}, 8) = 0
7601  getpid()                          = 7601
7601  kill(7601, SIGHUP)                = 0
7601  sigreturn()                       = ? (mask now [RTMIN])
7601  --- SIGHUP (Hangup) ---
7601  +++ killed by SIGHUP +++

Hope this helps.

Carlos
