Here's a clue:
peter@beast[8:06am]~-130> cat foo.c
int main(int ac, char *av[])
{
char *a = new char[10000];
}
peter@beast[8:07am]~-131> c++ -o foo foo.c
peter@beast[8:07am]~-132> ./foo
peter@beast[8:08am]~-133> c++ -static -o foo foo.c
peter@beast[8:08am]~-134> ./foo
Abort
peter@beast[8:09am]~-147> ktrace ./foo
Abort
peter@beast[8:09am]~-148> kdump
34729 ktrace RET ktrace 0
34729 ktrace CALL execve(0x11fff947,0x11fff758,0x11fff768)
34729 ktrace NAMI "./foo"
34729 foo RET execve 0
34729 foo CALL readlink(0x12000a154,0x11fff628,0x3f)
34729 foo NAMI "/etc/malloc.conf"
34729 foo RET readlink -1 errno 2 No such file or directory
34729 foo CALL mmap(0,0x2000,0x3,0x1002,0xffffffffffffffff,0,0)
34729 foo RET mmap 1610612736/0x160000000
34729 foo CALL break(0x120030000)
34729 foo RET break -1 errno 12 Cannot allocate memory
...
versus dynamic:
peter@beast[8:10am]~-152> ktrace ./foo
peter@beast[8:11am]~-153> kdump | more
35056 ktrace RET ktrace 0
35056 ktrace CALL execve(0x11fff947,0x11fff758,0x11fff768)
35056 ktrace NAMI "./foo"
35056 ktrace NAMI "/usr/libexec/ld-elf.so.1"
35056 foo RET execve 0
35056 foo CALL mmap(0,0x1590,0x3,0x1000,0xffffffffffffffff,0,0)
35056 foo RET mmap 1610792960/0x16002c000
35056 foo CALL munmap(0x16002c000,0x1590)
35056 foo RET munmap 0
35056 foo CALL __sysctl(0x11fff478,0x2,0x16012ccf8,0x11fff488,0,0)
35056 foo RET __sysctl 0
35056 foo CALL mmap(0,0x8000,0x3,0x1002,0xffffffffffffffff,0,0)
35056 foo RET mmap 1610792960/0x16002c000
[.. lots of ld.so stuff trimmed ...]
35056 foo CALL sigprocmask(0x3,0x16012d158,0)
35056 foo RET sigprocmask 0
35056 foo CALL readlink(0x16024204c,0x11fff628,0x3f)
35056 foo NAMI "/etc/malloc.conf"
35056 foo RET readlink -1 errno 2 No such file or directory
35056 foo CALL mmap(0,0x2000,0x3,0x1002,0xffffffffffffffff,0,0)
35056 foo RET mmap 1611612160/0x1600f4000
35056 foo CALL break(0x120014000)
35056 foo RET break 0
35056 foo CALL break(0x120018000)
35056 foo RET break 0
35056 foo CALL exit(0)
ie: we have this which works:
35056 foo CALL break(0x120014000)
35056 foo RET break 0
vs:
34729 foo CALL break(0x120030000)
34729 foo RET break -1 errno 12 Cannot allocate memory
It doesn't appear to be a resource limit though:
peter@beast[8:17am]~-172> cat foo.c
char buf[1000000];
int main(int ac, char *av[])
{
char *a = new char[10000];
}
peter@beast[8:17am]~-173> c++ -o foo foo.c
peter@beast[8:17am]~-174> ktrace ./foo
peter@beast[8:18am]~-175> kdump | grep break
36947 foo CALL break(0x120108000)
36947 foo RET break 0
36947 foo CALL break(0x12010c000)
36947 foo RET break 0
How strange..
Cheers,
