yes there is a limit, look at

getrlimit show the size as 4GiGs of RLIMIT_DATA on a 32-bit. which
means that its unlimited?

Thanks,

# man setrlimit

RLIMIT_DATA
              The maximum size of the process's data segment (initialized
data, uninitialized data, and heap).  This limit affects calls to brk(2) and
sbrk(2), which fail with the error ENOMEM  upon
              encountering the soft limit of this resource.

Hi all,

Is there any limit on the maximum data segment size used by c programs?

Thanks,
