I can't reproduce this. Even if gcc produced zero-length assembly (which it doesn't), the corresponding object file wouldn't be zero-length. So, either you have full disk, or assembler crashed. You can strace -f it to see what was going on. It appears this was due to corrupted .ccache!. After rm -rf ~/.ccache, seems to be fixed. What fun tracking this down. So a defect in ccache. But nasty. No segfault, no errors. Just quietly 0-length output. |
