Project: C++ Standard Library
Issue Type: Bug

Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.2.0/configure --prefix=/opt/compilers/gcc-4.2.0

Reporter: Liviu Nicoara
The following program asserts:
$ cat t.cpp
#include <string>
#include <assert.h>
int
main ()
{
assert (std::char_traits< char >::find ("a\201", 2, '\201'));
return 0;
}
$ make t && ./t
gcc -c -I/build/nicoara/stdcxx/include/ansi -D_RWSTDDEBUG
-I/build/nicoara/stdcxx/include -I/build/nicoara/stdcxx/build/include
-I/build/nicoara/stdcxx/examples/include -pedantic -nostdinc++ -g -W -Wall
-Wcast-qual -Winline -Wshadow -Wwrite-strings -Wno-long-long -Wcast-align
/build/nicoara/stdcxx/examples/manual/t.cpp
gcc t.o -o t -L/build/nicoara/stdcxx/build/lib -lstd11s -lsupc++ -lm
t: /build/nicoara/stdcxx/examples/manual/t.cpp:7: int main(): Assertion
`std::char_traits< char >::find ("a\201", 2, '\201')' failed.
Aborted
possibly because of the way memchr is used in include/rw/_traits.h:409
Thanks,
Liviu
