Have you been able to get the lto1 command line? I don't think I have seen a case where a direct invocation of lto1 would fail but it would work in gdb. Sounds like a memory problem, have you tried valgrind? Getting the command line is annoying. In part because of the many layers in part because of the use of @files. gcc -v -save-temps should print you the necessary command line, no? Are you using gold + plugin or collect2? > Thanks, > > Ciao! > Steven > Cheers, -- Rafael Ávila de Espíndola
