Tath's exactly wath i'm doing! Thats the weird thing...
char * res = (char ) malloc (100sizeof(char));
There is something wrong on how i declare it? I'm using the same code on my IDE and runs propperly

I'm having a problem and don't know how to solve it. (i'm using C).

Test Crashed
Caught unexpected signal: SIGSEGV (11). Invalid memory access.

I don't know where to look for it, i suppose it's in the allocation of memory but not sure how to solve it. I try rewrote the code almost completely and i keep getting it. Any ideas?

I do, i have a particular return for that type of cases.
The first 2 test cases are successful, after that i got the error. Sorry, i should have said it before.

I'm having a problem to solve this kata in C. I got the following error:

Test Crashed Caught unexpected signal: SIGSEGV (11). Invalid memory access.

I've never got it before and couldn't find any usefull information about it. I try the same code i use here on my own compiler and works perfectly, at least with the test cases shown.
