Compiling with debugger flag -g fixes SEGfault (fortran90)

So the title kinda says it all. I was getting a SEGfault, so I decided to compile with the -g option to find where, and low and behold the SEGfault doesn't occur.

I suppose the answer is "Problem solved! You fixed yet another SEGfault." But I am very curious how this could have happened.

Some info that may help:
1 At first the executable instantly killed itself. After removing some unnecessary variables from the header file, this was fixed. (stack overflow i assume)
2 This is the full compilation command:
ifort -r8 -i4 -mcmodel=large -i-dynamic -align all -g -o code code.f90
3 When compiling without debugger flag messages informing me that loops have been vectorized are printed to screen. Nothing is printed to screen when I compile WITH '-g'.

Thanks!
