Unhandled exception at 0x93b3237d in project00.exe: 0xC0000005: Access violation - c++

Question

In my program when i exit the section of ASM code and returning to the C++ code i get the Unhandled exception at 0x93b3237d in project00.exe: 0xC0000005: Access violation. In Crtexe.c at line mainret = main(argc, argv, envp); and in the disassembly when the 0C is add to ESP. i think the problem might be the return address of the main function is get corrupted before returning and that causing it to fail. Program find the intersection and union of two sets. Using VS10 and am out of ideas.

Probably a dumb comment since I've never done any x86 assembly. But I thought asm was inline? So what is your first 'ret' actually returning from?
