Dear friendly Debian GCC folks, I believe I've encountered this bug as well. Here's the scenario: I'm starting to work on a package (homework, so I'm starting with half a dozen source files alreay), tinkering away, happily compiling, when suddenly:
In file included from /usr/include/string.h:114, from /usr/include/c++/3.3/cstring:51, from /usr/include/c++/3.3/bits/char_traits.h:45, from /usr/include/c++/3.3/string:47, from scene.h:1, from createdata.cpp:1: /usr/include/xlocale.h:29: internal compiler error: Segmentation fault ... and following this, all other files I try, which only a few minutes ago compiled *just fine*, fail with the same error. Compiler flags don't seem to matter. This is with g++3.3 version 1:3.3.4-13. After "apt-get install --reinstall g++-3.3", everything is back to normal... ??? Thanks, Reid p.s. I do observe the bug number contains the string '666'. Hmmmm.... ;)
