my_string ms(std_string.c_str(), shm_allocator);

or

my_string ms(std_string.begin(), std_string.end(), shm_allocator);

There area many possible ways using my_string constructor. You must 
always pass an allocator.

However I don't think that's your problem. Do you have internal zero 
bytes in "char *data"? Just check if strlen(data) is equal to 
data_to_share.size(). If you have internal zeroes, use

(data_to_share.begin(), data_to_share.end(), 
managed_shm.get_segment_manager());

to build the shared memory string.

Best,
