Use the function thread_alloc::get_memory instead.

Syntax
# include <cppad/utility/omp_alloc.hpp>
v_ptr = omp_alloc::get_memory(min_bytes, cap_bytes)

Purpose
Use omp_alloc to obtain a minimum number of bytes of memory (for use by the current thread ).

min_bytes
This argument has prototype
     size_t min_bytes
It specifies the minimum number of bytes to allocate.

cap_bytes
This argument has prototype
     size_t& cap_bytes
It's input value does not matter. Upon return, it is the actual number of bytes (capacity) that have been allocated for use,
     min_bytes <= cap_bytes

v_ptr
The return value v_ptr has prototype
     void* v_ptr
It is the location where the cap_bytes of memory that have been allocated for use begins.

Allocation Speed
This allocation should be faster if the following conditions hold:

1. The memory allocated by a previous call to get_memory is currently available for use.
2. The current min_bytes is between the previous min_bytes and previous cap_bytes .

Example
omp_alloc.cpp
