Comment 1 Jakub Jelinek 2001-10-19 16:24:25 UTC
Compile what?
If it is reproduceable (ie. always ICEs on the same input with the same options,
you need to provide
a) full gcc or g++ command line
b) rerun it with -save-temps option in addition to what you used to reproduce
   it and attach here the .i or .ii file it creates

Comment 2 Jakub Jelinek 2001-10-23 15:21:27 UTC
Please use -fno-builtin switch. linux/string.h conflicts with g++ builtins.
If you used <string.h> instead, it would work just fine.
This problem was "solved" in gcc3 by hardcoding -fno-builtin for C++
and relying on libstdc++-v3 headers to map those functions to the
__builtin_* counterparts. But libstdc++ (v2) doesn't do this and IMHO
disabling builtin optimizations for C++ for all folks just to get rid of this
ICE is not a good idea.
BTW: Just wondering: since when are kernel modules written in C++ and use libc headers?
