The function
swapNames
in pointers-struct.c and enums.c have an incorrect function signature. If we're swapping what username and password point to as it seems to be the case when calling theswapNames
function frommain
, both parameters should be of typechar **
and notchar *
.This change also fixes the ELF generated which seems to be swapping just the first character of an address instead of swapping the strings. In reality it only works as both argv[2] and argv[3] are very close and we're just changing the last byte of the address. There could be cases where the addresses of argv[2] and argv[3] have the last two bytes which are different
Also removed unnecessary
malloc
which was also not beingfree
d.Should this pull request be accepted, the relevant binaries would also need to be updated
