[Bug libstdc++/14098] New: typeinfo issue with __gnu_cxx::stdio_sync_filebuf

[Richard dot Kreckel at Framatome-ANP dot com]

Consider this program:

#include <iostream>
#include <typeinfo>
#include <ext/stdio_sync_filebuf.h>
using namespace std;
typedef __gnu_cxx::stdio_sync_filebuf< char > unix_sync_filebuf_t;
int main()
{
    if ( dynamic_cast< unix_sync_filebuf_t* >( cout.rdbuf() ) ) {
	cout << "It's a C FILE." << endl;
    }
}

$ g++-3.4-20040206 test.cc
/tmp/cckpk27u.o(.text+0x13d): In function `main':
: undefined reference to `typeinfo for __gnu_cxx::stdio_sync_filebuf<char,
std::char_traits<char> >'
collect2: ld returned 1 exit status

Compiling statically fixes the problem:

$ g++-3.4-20040206 test.cc -static  &&  ./a.out
It's a C FILE.

Maybe this could be related to PR14097.

Confirmed, it works on my powerpc-apple-darwin7.2.0 box just fine (which by the way does not have 
weak symbols but shared libraries) but not on my i686-pc-linux-gnu box, this is with 3.5.0.

This is actually a library bug.  Related to export symbol list on platforms
which implement hidden symbols (i.e. why not seen on darwin).  Working
on fix.
