[ic] interchange general protection error in libc

[marco]

 From previous segment fault at 80c I have reinstalled 
Bundle::Interchange without errors, reinstalled interchange 5.6.3 from 
source following step by step the procedure but on make test:
____________________________________
server/unixmode.......ok 1
server/startup........ok 2
link/unixmode.........not ok 3
# When the above test fails, it may be due to your ISP or some other
# mechanism blocking port 8786.
<snip>
6 tests run -- 4/6 failed.
make: *** [test_dynamic] Error 1


My server runs with unixmode so I have continued doing

make install

and despite these errors now all old catalogs run but, only in 
interchange restart, general protection error libc persist

general protection ip:b769338a sp:bfb0f30c error:0 in 
libc-2.11.3.so[b75ce000+140000]

I cannot put this server in production before i understand what is this 
error. Digged mailing list without any results. Have you any hint, 
suggestion or test to do ?

Thanks to all.
