Hello, I am now convinced this is a g++ bug. I could reproduce the FTBFS on qemu. Trying to compile omniorb4 with g++-4.1.3 20080114 (Debian 4.1.2-19) succeeds. I will try to write a reduced test case before submitting the bug report on g++-4.2. I need to check wether g++-4.3 is affected as well. Anyway, I'll prepare an upload using g++-4.1 on arm tomorrow to fix this FTBFS. Regards, Thomas
