Compiler/TDA2EVM5777: Issue while overloading delete operator

Please show us an example of code which calls your delete macro and for which the TI compiler fails to call deletep

Hi

I can provide an example that works with linux , which is as follows

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
void operator delete(void *);
void operator delete[](void *);
void deletep(const char *, int);

inline const char * print_file_name(const char *path)
{
for (size_t i = strlen(path) - 1; i; i--)
{
if ((path[i] == '/') || (path[i] == '\\'))
{
return &path[i + 1];
}
}
}

void operator delete(void *pfs)
{
printf("deleted address: %x \n", pfs);
free(pfs);
return;
}

void operator delete[](void *pfs)
{

operator delete(pfs);
}

void deletep(const char *file, int lineno)
{

const char *fname_delete;
fname_delete = print_file_name(file);
printf("Memory deleted @ file %s \t ", fname_delete);
printf("Line number %d \n ", lineno);

return;
}

#define delete deletep(__FILE__, __LINE__),delete

class aclass
{
private:
int num;
char mychar;
public:
aclass(int num, char mychar) :num(num), mychar(mychar) {}
aclass() { num = 0; mychar = 'a'; }
};

int main(int argc, char *argv[])
{
int *a = new int(100);
aclass *b = new aclass(100, 'b');
aclass *c = new aclass[2];
delete a;
delete b;
delete[] c;
return 0;

}

Make sure function print_file_name returns a value even when you don't find a directory separator in the pathname. When I fix this and compile with C6x compiler version 7.4.19, I get what appears to be the correct answer:

Memory deleted @ file foo.cpp Line number 61
deleted address: 80006008
Memory deleted @ file foo.cpp Line number 62
deleted address: 80006018
Memory deleted @ file foo.cpp Line number 63
deleted address: 80006028

Make sure you have enough stack and heap space. What version of the compiler are you using?

Hi 

Thanks for the reply. I am using gcc-arm-none-eabi-4_7-2013q3 compiler for A15. Can you please compile using the gcc version which i have mentioned and execute the program?
