f# stackoverflow project euler #4

Question

I\'m working on problem four of Project Euler and am running into a stackoverflow exception. I\'m not asking for help on solving the problem, I\'d just like it explained

Answer 1

I can't read F# and don't know if your problem is related to this but especially if you're doing something recursive avoid checking for equality to a number, instead try to check for a threshold. For example, instead of testing n = 0, test n <= 0.

Answer 2

Are you compiling in 'Debug' mode or 'Release' mode? Debug mode in VS has tail calls turned off by default (compiler flag "--tailcalls-"), in order to preserve stacks for debugging, but this has the trade-off that you may StackOverflow. You can either switch to 'Release' mode, or

• right-click the project properties in Solution Explorer, select 'Properties'
• go to the 'Build' tab
• make sure 'Debug' configuration is selected
• click the box 'Generate tail calls'

to turn on tail calls with 'Debug' settings.

(Your program runs fine for me with tail calls enabled.)
