I set up a chroot environment and run the test-eh tests:

On i686:
glibc (includes Jakub's patch) compiled with GCC 2.95.3+some patches
Tests with GCC 2.95.3: Successful

Installed gcc 3.0.1 in the chroot
Tests with GCC 3.0.1: Successfull

Rebuild glibc with GCC 3.0.1 and installed this glibc:
Tests with GCC 3.0.1: Succesfull

Tests with GCC 2.95.3 after removing libgcc_s.so from ld.so.cache:
./app
tsearch
make: *** [check] Aborted

Adding libgcc_so.so again gives the same result:
amdsim0:/tmp/test-eh# LD_DEBUG=libs ./app
23780:  find library=libstdc++-libc6.2-2.so.3; searching
23780:   search cache=/etc/ld.so.cache
23780:    trying file=/usr/lib/libstdc++-libc6.2-2.so.3
23780:
23780:  find library=libm.so.6; searching
23780:   search cache=/etc/ld.so.cache
23780:    trying file=/lib/libm.so.6
23780:
23780:  find library=libc.so.6; searching
23780:   search cache=/etc/ld.so.cache
23780:    trying file=/lib/libc.so.6
23780:
23780:
23780:  calling init: /lib/libc.so.6
23780:
23780:

23780:
23780:
23780:  calling init: /usr/lib/libstdc++-libc6.2-2.so.3
23780:

23780:  initialize program: ./app
23780:
23780:
23780:  transferring control: ./app
23780:
tsearch
Aborted

dso-app and dso-load-app also fail:
amdsim0:/tmp/test-eh# ./dso-app 
tsearch
Aborted
amdsim0:/tmp/test-eh# ./dso-load-app 
tsearch
Aborted

but the dso-*c-app tests work. According to your comments this is
expected, isn't it?

Andreas

Btw. successfull tests mean:
