Bug#244835: apt-get: hangs with long value in config file

[Gerrit Pape <pape-dbnbgs@smarden.org>]

Package: apt
Version: 0.5.24

Hi, when putting this into etc/apt/apt.conf.d/99test, apt-get hangs in
an infinite loop it seems:

# cat /etc/apt/apt.conf.d/99test 
DPkg
{
  Post-Invoke {"echo 678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901";}
}
# apt-get install --reinstall sed
...

This works:

# cat /etc/apt/apt.conf.d/99test 
DPkg
{
  Post-Invoke {"echo 67890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890";}
}

With another syntax, this hangs:

# cat /etc/apt/apt.conf.d/99test 
DPkg::Post-Invoke {"echo 6789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456";};
# apt-get install --reinstall sed
...

and this works:

# cat /etc/apt/apt.conf.d/99test 
DPkg::Post-Invoke {"echo 678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345";};
