>Description:
When invoking gcc with the -finput-charset=iso-8859-1 option, it fails with an internal compiler error. This can be easily reproduced by trying to compile an empty source file with this option.

Error is :
  $ echo > empty.cpp
  $ gcc -c empty.cpp -finput-charset=iso-8859-1
    cc1plus: internal compiler error: Segmentation fault: 11
    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <URL:http://gcc.gnu.org/bugs.html> for instructions.
  $ gcc -v
    Using built-in specs.
    Target: amd64-undermydesk-freebsd
    Configured with: FreeBSD/amd64 system compiler
    Thread model: posix
    gcc version 4.2.1 20070719  [FreeBSD]

>How-To-Repeat:
echo > empty.cpp
gcc -c empty.cpp -finput-charset=iso-8859-1
