it should still fix some issue I have a memory corruption that I have no clue what is happening. There is a piece of my code: , Superficially, your problem is:
code :
t_data_thread *t = malloc(sizeof(t_data));
t_data_thread *t = malloc(sizeof(*t));

can memory corruption be caused by invalid *reading* freed memory?

it should still fix some issue You can use GDB to watch each write in this memory address, like this:
code :
(gdb) watch *((int*)0xf28000fa)

help you fix your problem The code is broken. If the malloc would return already properly aligned address, say 0 and you request 8 byte aligned address, the code will return address 4, which is obviously wrong. The following line should be removed:
unsigned* ptrAdjustment = reinterpret_cast( alignedAddress - 4 );

With these it helps Problem solved.
Thought I'd add it here on the off chance anyone else ever does the same thing.

it should still fix some issue "Memory corruption" is not a formal term, so it is not very meaningful to go look for a formal definition. Also, Wikipedia is not necessarily a canonical source of information.
A null pointer access may or may not lead to memory corruption. Mostly this depends on if the system allows writes to address 0 or not1).

I wish this helpful for you You allocate n bytes but you want to allocate space for n ints. An int is (usually) more than one byte.
Change malloc(n) to malloc(n*sizeof(int)).
