I looked more into. In fact I do not understand what the test tries to test. It effectively test return code of
fprintf (fp, "%2147483648d%2147483648d", 1, 1); The printf family returns int and should return number of written bytes. It therefore cannot exceed MAX_INT. But the test tries to print twice entry with width MAX_INT+1. I would understand the test with i.e. 2147483640 or six time 512 MB. On kfreebsd-amd64, it tries to mmap(0,0xffffffff80001000,PROT_READ|PROT_WRITE,MAP_ANON|MAP_TYPE|MAP_PRIVATE,0xffffffff,0) and fails. On kfreebsd-i386, it tries to mmap 2GB and it succeeds. mmap(0,0x80001000,PROT_READ|PROT_WRITE,MAP_ANON|MAP_TYPE|MAP_PRIVATE,0xffffffff,0) And after that there are (at least) three posibilities. - available memory is "low" (aka 2GB of RAM and no swap) -> Didn't expect signal from child: got `Killed' - available "fast" memory is "low" (aka 2GB of RAM and 2GB of swap) -> Timed out: killed the child process - available "fast" memory is "enough" (aka 3GB of RAM or fidling with TIMEOUTFACTOR=5) -> test succeeds The memory map before mmap of 32-bit process. # cat /proc/XXX/maps 08048000-0804a000 r-xp 00008000 00:00 2320432 bug22 0804a000-0804b000 r--p 00008000 00:00 2320432 bug22 0804b000-0806d000 rw-p 00022000 00:00 0 2804a000-28066000 r-xp 0001e000 00:00 589760 lib32/ld-2.13.so 28066000-28067000 r--p 0001e000 00:00 589760 lib32/ld-2.13.so 28067000-28069000 rw-p 00002000 00:00 0 28069000-2806e000 r--p 00005000 00:00 497370 ld.so.cache 2806e000-28192000 r-xp 00128000 00:00 589763 lib32/libc-2.13.so 28192000-28194000 r--p 00128000 00:00 589763 lib32/libc-2.13.so 28194000-28195000 rw-p 00128000 00:00 589763 lib32/libc-2.13.so 28195000-28199000 rw-p 00004000 00:00 0 fffdf000-fffff000 rwxp 00020000 00:00 0 1161 bug22 NAMI "/dev/null" 1161 bug22 RET open 3 1161 bug22 CALL mmap(0,0x80001000,PROT_READ|PROT_WRITE,MAP_ANON|MAP_TYPE|MAP_PRIVATE,0xffffffff,0,0) 1161 bug22 RET mmap 672763904/0x28199000 1161 bug22 PSIG SIGKILL SIG_DFL Petr -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
