No __cxa_get_exception_ptr symbol in libstdc++

Description of problem: while linking application with g++4 (gcc402), the error appears, that there is no symbol __cxa_get_exception_ptr It should be in libstdc++, but it's not. Version-Release number of selected component (if applicable): gcc-c++ 4.0.2 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
It is not included there because RHEL4 includes libstdc++ from GCC 3.4.5-RH, rather than 4.0.x. But, g++4 included in RHEL4 has been patched not to ever use that symbol, see gcc4-c++-pr10606-revert.patch in src.rpm. I don't see how you can get that error unless you are using your own GCC 4.0.x build rather than the one included in RHEL4.
In fact I was using 4.0.2 from FC, but when I saw RH released 4.0.2 version, I reinstalled whole development packages (gcc*, cpp, binutils, libtools, libgcc, libstdc++ and some more). However the symbol is still in use. It's little strange, but only one object requires this(unfortunatelly I can't show it to You...). Adding -lsupc++ to the linking phase helped, but it's not what I looked for.
Well, in fact I have to apologize. It appeard to be problem with ccache was not cleared. ccache -C was not enought, but rm -rf /tmp/ccache fixed the thing. Sorry and thanx. MArk is as a NOTaBUG
