Hi Masaharu,

Philippe asked me for the same details.  I have attached the emails hat I
sent him, which includes all of the details that reproduce the problem.
FYI, I first encountered the problem using ROOT 2.25.03.  However, the
problem disappeared in ROOT 2.26.01.

Thank you for your help.

Regards, Matt

Hi Philippe, I'm using ROOT 2.25.03 on RedHat Linux 6.1 Intel, but I used gcc 2.95.2 to compile ROOT instead of egcs 1.1.2. I built ROOT from source using the following configure line: export CERNLIB= /usr/local/cern/2000/lib export TTF_FONTDIR=/usr/local/root/2.25.03/gcc-c++-2.95.2/ttf/fonts ./configure linuxegcs --with-cern-libdir="$CERNLIB" --with-ttf-fontdir="$TTF_FONTDIR" I also used a personal MyConfig.mk file with the following single line: EXTRA_LDFLAGS = -Wl,-rpath,$(ROOTSYS)/lib I also made two personal bugfixes to my installation of gcc-2.95.2 which make my compiler different than a "vanilla" build of gcc-2.95.2 under Linux. I changed the bitset header (/usr/local/include/g++-3/bitset on my system) since bitsets were broken. I also removed the "#define __STL_NO_NAMESPACES" from the stl_config.h header (/usr/local/include/g++-3/stl_config.h on my system) to enable namespace std. I have included two patches of my gcc-2.95.2 source tree against a "vanilla" gcc-2.95.2 source tree so that you can see exactly what changes I made. The "STL vector + class pointer" problem is easily reproducible on my system. If there is any other information I can give you , please let me know. Thanks for your help Philippe.

Hi Philippe, I just tested my "STL vector + class pointer" problem on the cvs sources based on the v2-26-01 tag (compiled with my "custom" gcc-2.95.2 on RedHat Linux 6.1 Intel). The problem has disappeared with this release, i.e. everything works fine on ROOT 2.26.x. Is there a cvs branch for bug fixes, etc. for the v2-25-final tag? Or, should we assume that this particular STL bug won't be fixed for the ROOT 2.25.x source base, and so we should therefore migrate to the 2.26 source base? If so, would you consider the ROOT 2.26.x source base stable enough to begin migrating too? Thanks for your help.
