Failure while calling a function in GDB session

Hi All,
I compiled the following code on my linux PC using clang with PIE option-

struct struct4 {char a; char b; char c; char d; };
struct struct4 foo4 = {'a','2','c','4'};
struct struct4 fun4()
  return foo4;

int main()
return 0;

clang -g -fPIE structs.c

In GDB session when i call p/c fun4() i get something like below-
(gdb) p/c fun4()
Cannot access memory at address 0x34633261

Disassemble of the code is as follows -

(gdb) disassemble
Dump of assembler code for function fun4:
   0x080483e0 <+0>: call 0x80483e5 <fun4+5>
   0x080483e5 <+5>: pop %eax
   0x080483e6 <+6>: add $0x1c0f,%eax
   0x080483ec <+12>: mov 0x4(%esp),%ecx
   0x080483f0 <+16>: mov -0x8(%eax),%eax
   0x080483f6 <+22>: mov (%eax),%eax
=> 0x080483f8 <+24>: mov %eax,(%ecx)
   0x080483fa <+26>: ret $0x4
End of assembler dump.
(gdb) i r

ss 0x7b 123
ds 0x7b 123
es 0x7b 123
fs 0x0 0
gs 0x33 51

Seems value in EAX register is getting corrupted in this case as a result of
mov (%eax),%eax Call.
Could anyone guide me how i can fix this issue and which part of code to look into.


Hi Guys any inputs on this issue?
