A run with -c move_pages runs and runs. Yeah, I still see it with the current snapshot. But, not with move_pages anymore, it seems. There had to be more sources, the current one is (with -x move_pages): *** Error in `trinity': double free or corruption (top): 0x00000000014f9bc0 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x740af)[0x7f0c48ba30af] /lib64/libc.so.6(+0x798de)[0x7f0c48ba88de] /lib64/libc.so.6(+0x7a5e6)[0x7f0c48ba95e6] trinity[0x40abc8] trinity[0x40dabc] trinity[0x40338a] trinity[0x40704c] trinity[0x402c47] /lib64/libc.so.6(__libc_start_main+0xf5)[0x7f0c48b50b15] trinity[0x402f13] The topmost trinity item 0x40abc8 is "entry->post(childno)".
