Problem Text | When a process has a ~4 GiB address space available, the test segfaults. This is strace output from a process with a ~4 GiB address space instead of a 3 GiB address space: 3 GiB: chmod("/tmp/vsrt_mmap", 0777) = 0 open("/tmp/vsrt_mmap", O_RDWR) = 5 mmap2(NULL, 1073766400, PROT_WRITE, MAP_SHARED, 5, 0) = 0x77480000 mmap2(NULL, 12288, PROT_NONE, MAP_SHARED, 5, 0) = 0x7747d000 munmap(0x7747d000, 12288) = 0 mmap2(0x7747d000, 2147528704, PROT_WRITE, MAP_SHARED|MAP_FIXED, 5, 0) = -1 ENOMEM (Cannot allocate memory) close(5) = 0 4 GiB: 3039 chmod("/tmp/vsrt_mmap", 0777) = 0 3039 open("/tmp/vsrt_mmap", O_RDWR) = 5 3039 mmap2(NULL, 1073766400, PROT_WRITE, MAP_SHARED, 5, 0) = 0x4018a000 3039 mmap2(NULL, 12288, PROT_NONE, MAP_SHARED, 5, 0) = 0x40017000 3039 munmap(0x40017000, 12288) = 0 3039 mmap2(0x40017000, 2147528704, PROT_WRITE, MAP_SHARED|MAP_FIXED, 5, 0) = 0x40017000 3039 --- SIGSEGV (Segmentation fault) @ 0 (0) --- 3039 --- SIGBUS (Bus error) @ 0 (0) --- 3039 --- SIGSEGV (Segmentation fault) @ 0 (0) --- 3039 +++ killed by SIGSEGV +++ |
