[cl-debian] Bug#462742: Consumes 100% CPU if terminal window is closed

[Chris Lamb]

Package: clisp
Version: 1:2.43-2

Starting an interactive CLISP session in a gnome-terminal window and then
closing the said window causes the CLISP process to start consuming 100%
CPU.

Stracing the process highlights a number of segfaults along the lines of:

   mmap(0x333e43000, 4096, PROT_READ|PROT_WRITE,
       MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x333e43000
   --- SIGSEGV (Segmentation fault) @ 0 (0) ---
   mprotect(0x333cf8000, 4096, PROT_READ|PROT_WRITE) = 0
   rt_sigreturn(0x333cf8000)               = 13754138688
   --- SIGSEGV (Segmentation fault) @ 0 (0) ---
   mprotect(0x333cf9000, 4096, PROT_READ|PROT_WRITE) = 0
   rt_sigreturn(0x333cf9000)               =  13754142840
   --- SIGSEGV (Segmentation fault) @ 0 (0) ---
   mprotect(0x333d37000, 4096, PROT_READ|PROT_WRITE) = 0
   rt_sigreturn(0x333d37000)               = 13754397368

   (etc.)

I can reproduce on i386 and amd64 machines.
