Problem with Submission in Coding Blocks IDE

Could you please fix your compiler, because most of the codes that i try to submit here are either falling into infinite loop or sometimes it doesn’t even show any output. How will I be able to get my certificate if this thing continue? Please fix it as soon as possible. I tried Activity Selection, next Permutation, and even more, these are working fine on my machine as well as online. So it is humble request to Coding Blocks team to fix these issues as soon as possible.
