Exception "AES: 4 is not a valid key length" on BegleboneBlack - encryption

Question

I installed Crypto++ on BeagleBone black by following native installation method provided at ARM (Command Line). Then when I ran cryptest.sh, it runs smoothly.
Here is my small test-code to test Crypto++ functionality.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdint.h>
#include "libcryptoWrapperGCM.h"
int main(int argc,char* argv[]){
byte key[] = "123456789012345";
byte vi[] = "123456789012345";
char p[205] = { 0x00, 0x01, 0x00, 0x25, 0x00, 0x00, 0x00, 0x09,
0x00, 0x01, 0x00, 0x05, 0x6f, 0x74, 0x6f, 0x63, 0x6e, 0xf0, 0x01, 0x00, 0x14, 0x00, 0x01, 0x00,
0x06, 0x70, 0x61, 0x72, 0x61, 0x6d, 0x31, 0x00, 0x01, 0x00, 0x06, 0x70, 0x61, 0x72, 0x61, 0x6d,
0x32, 0xf0, 0x02, 0x00, 0xa0, 0x00, 0x23, 0x00, 0x40, 0x38, 0x34, 0x32, 0x33, 0x32, 0x30, 0x33,
0x34, 0x62, 0x66, 0x61, 0x36, 0x38, 0x38, 0x32, 0x38, 0x30, 0x64, 0x37, 0x36, 0x38, 0x35, 0x64,
0x39, 0x66, 0x62, 0x62, 0x65, 0x36, 0x34, 0x32, 0x37, 0x36, 0x37, 0x36, 0x33, 0x34, 0x61, 0x64,
0x36, 0x34, 0x37, 0x32, 0x66, 0x66, 0x37, 0x33, 0x63, 0x33, 0x34, 0x32, 0x65, 0x63, 0x34, 0x32,
0x35, 0x38, 0x31, 0x35, 0x37, 0x66, 0x61, 0x33, 0x61, 0x00, 0x24, 0x00, 0x40, 0x36, 0x35, 0x30,
0x38, 0x63, 0x39, 0x31, 0x36, 0x63, 0x37, 0x39, 0x30, 0x63, 0x66, 0x37, 0x33, 0x34, 0x61, 0x31,
0x64, 0x34, 0x35, 0x65, 0x30, 0x32, 0x62, 0x30, 0x64, 0x39, 0x61, 0x39, 0x65, 0x37, 0x35, 0x36,
0x37, 0x34, 0x66, 0x36, 0x64, 0x61, 0x62, 0x31, 0x63, 0x61, 0x30, 0x32, 0x64, 0x31, 0x64, 0x66,
0x64, 0x37, 0x39, 0x63, 0x66, 0x39, 0x35, 0x38, 0x35, 0x64, 0x36, 0x31, 0x33, 0x00, 0x25, 0x00,
0x08, 0x00, 0x00, 0x00, 0x00, 0x57, 0x16, 0x69, 0x13, 0x00, 0x26, 0x00, 0x08, 0x00, 0x00, 0x00,
0x00, 0x00, 0x06, 0x0b, 0x94};
char *p_data_ptr = p;
byte *ebuffer = malloc(205+12);
char *d = GcmEncode(key,vi, p_data_ptr,205,ebuffer,0);
int i ;
for(i=0; i< 205+12; i++){
printf("0x%02x, ",ebuffer[i] & 0xff);
}
char *buffer = malloc(205);
char* decodedMessage = GcmDecode(key, vi,ebuffer, 217,buffer,0);
return 1;
}
When I run the program I get Exception:
terminate called after throwing an instance of 'CryptoPP::InvalidKeyLength'
what(): AES: 4 is not a valid key length
Aborted
The odd thing is that it only happens on BeagleBone Black and not x86 machine, even though both have Ubuntu 14.04.
Any idea how to solve this issue? Thank you.
Edit 1:
Here is the wrapper source:
#include "gcm.h"
using CryptoPP::GCM;
#include "assert.h"
extern "C" {
const char* GcmEncode(byte key_hash[],byte iv_hash[], byte* p_data_ptr,size_t length,uint8_t* destination, int offset) {
string cipher,encoded;
encoded.clear();
GCM< AES >::Encryption e;
e.SetKeyWithIV( key_hash, sizeof(key_hash), iv_hash, sizeof(iv_hash) );
const int TAG_SIZE = 16;
StringSource(p_data_ptr,length, true,
new AuthenticatedEncryptionFilter( e,
new StringSink( cipher ), false, TAG_SIZE)
);
encoded.clear();
StringSource(cipher, true,
new HexEncoder(new StringSink( encoded ))
);
memcpy(&(destination[offset]),cipher.c_str(),length+12);
return cipher.c_str();//NEED TO BE FREED IN FOLLOWING METHOD
}
const char *GcmDecode(byte key_hash[], byte iv_hash[], byte *cipher_ptr,size_t length, uint8_t* destination, int offset){
size_t pLength = length - 16;
string rpdata;
const int TAG_SIZE = 16;
GCM< AES >::Decryption d;
d.SetKeyWithIV(key_hash, sizeof(key_hash), iv_hash, sizeof(iv_hash));
AuthenticatedDecryptionFilter df(d,new StringSink( rpdata ),
AuthenticatedDecryptionFilter::DEFAULT_FLAGS,
TAG_SIZE
);
StringSource(cipher_ptr,length, true,new Redirector(df));
bool b = df.GetLastResult();
if( true == b ){
memcpy(&(destination[offset]),rpdata.c_str(),pLength);
return NULL;//NEED TO BE FREED IN FOLLOWING METHOD
}
else{
return NULL;
}
}
}
And this is the valgrind output:
