[Bug c++/24272] strange link error with ACE

This bug is not a dupliate of bug 19664.  I just applied
'gcc-push-pop-visibility.patch' to gcc 4.0.2 on 'x86_64'
and the problem is still there:

/usr/bin/ld: .shobj/Logging_Strategy.o: relocation R_X86_64_PC32 against
`std::basic_ofstreamchar, std::char_traitschar ::basic_ofstream(char
const*, std::_Ios_Openmode)@@GLIBCXX_3.4' can not be used when making a shared
object; recompile with -fPIC   

BTW, had to had-edit the patch for three files:

libstdc++-v3/include/tr1/array
libstdc++-v3/include/debug/string
libstdc++-v3/include/std/std_sstream.h

[Bug libstdc++/25719] ostringstream::str().c_str() returns pointer to unallocated memory

The string object in the test case does not die until the
'main' function is exited.  The destructor is not called
before the 'return' statement, which is after the 'printit'
function call.

Never mind.  Your are correct.  Got bit by the temporary object.
I'd turn that language feature off if I could.

[Bug libstdc++/25719] New: ostringstream::str().c_str() returns pointer to unallocated memory

[lawless at spamcop dot net]

The 'c_str()' method of the STL 'basic_string' class template
returns a pointer to free memory when called against a
string returned by the 'str()' method of the 'basic_ostringstream'
class template.  ISO/IEC 14882 [21.3.6] indicates pointers returned
by 'c_str()' should be good until the next non-const member of the
string object is called.

This behavior is confirmed by both 'purify' and 'mudflap'.
The same test case runs clean with 'purify' on Solaris 8
with the Sun Studio 5.4 compiler.
