<h3><details><summary>Original Reporter info from Mantis: <small>Cyrax</small></summary><small> - **Reporter name:** </small></details></h3> ## Description: I noticed this bug during my debugging session on why lazbuild fails randomly by trying to limit how much stack is reserved on program and threads it creates (https://bugs.freepascal.org/view.php?id=37179) Also setting stack values (namely rlim_cur) will fail under i386-linux. x86_64-linux target does not inhibit this problem. Fix is to change calls to syscall_nr_getrlimit, syscall_nr_ugetrlimit and syscall_nr_setrlimit to syscall_nr_prlimit64 one. See attached test project (project1.zip) and patch (ossysc.inc.diff) for more info. ## Additional information: test project output under i386-linux target:<br/> <pre> syscall_nr_getrlimit : success TRUE syscall_nr_getrlimit : alimits.rlim_cur 9223372032568197120 syscall_nr_getrlimit : alimits.rlim_max 0 syscall_nr_ugetrlimit : success TRUE syscall_nr_ugetrlimit : alimits.rlim_cur 18446744069422972928 syscall_nr_ugetrlimit : alimits.rlim_max 0 syscall_nr_getrlimit : success TRUE syscall_nr_getrlimit : blimits.rlim_cur 9223372032568197120 syscall_nr_getrlimit : blimits.rlim_max 0 set syscall_nr_setrlimit : blimits.rlim_cur 2097152 syscall_nr_setrlimit : success FALSE syscall_nr_setrlimit : blimits.rlim_cur 2097152 syscall_nr_setrlimit : blimits.rlim_max 0 syscall_nr_getrlimit : success TRUE syscall_nr_getrlimit : blimits.rlim_cur 9223372032568197120 syscall_nr_getrlimit : blimits.rlim_max 0 get syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : alimits.rlim_cur 8388608 get syscall_nr_prlimit64 : alimits.rlim_max 18446744073709551615 get syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : alimits.rlim_cur 8388608 get syscall_nr_prlimit64 : alimits.rlim_max 18446744073709551615 set syscall_nr_prlimit64 : alimits.rlim_cur 2097152 set syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : alimits.rlim_cur 2097152 get syscall_nr_prlimit64 : alimits.rlim_max 18446744073709551615 </pre> \--- test project output under x86_64-linux target:<br/> <pre> syscall_nr_getrlimit : success TRUE syscall_nr_getrlimit : alimits.rlim_cur 8388608 syscall_nr_getrlimit : alimits.rlim_max 18446744073709551615 syscall_nr_getrlimit : success TRUE syscall_nr_getrlimit : blimits.rlim_cur 8388608 syscall_nr_getrlimit : blimits.rlim_max 18446744073709551615 set syscall_nr_setrlimit : blimits.rlim_cur 2097152 syscall_nr_setrlimit : success TRUE syscall_nr_setrlimit : blimits.rlim_cur 2097152 syscall_nr_setrlimit : blimits.rlim_max 18446744073709551615 syscall_nr_getrlimit : success TRUE syscall_nr_getrlimit : blimits.rlim_cur 2097152 syscall_nr_getrlimit : blimits.rlim_max 18446744073709551615 get syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : alimits.rlim_cur 2097152 get syscall_nr_prlimit64 : alimits.rlim_max 18446744073709551615 get syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : alimits.rlim_cur 2097152 get syscall_nr_prlimit64 : alimits.rlim_max 18446744073709551615 set syscall_nr_prlimit64 : alimits.rlim_cur 2097152 set syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : success TRUE get syscall_nr_prlimit64 : alimits.rlim_cur 2097152 get syscall_nr_prlimit64 : alimits.rlim_max 18446744073709551615 </pre> ## Mantis conversion info: - **Mantis ID:** 37345 - **OS:** Arch - **OS Build:** 3.17.4-1 - **Build:** r45773 - **Platform:** Linux x86_64 - **Version:** 3.3.1
