RE: Recursion Limit - dbox - 05-29-2023
Yeah, I was really just altering the version Charlie was trying to run in qbjs. It is really expected that with no delay to give control back to the display a runaway recursive function would just crash the system in qb64 or qbjs.

Here is code I checked with, maybe there is better?
Code: (Select All)howRecursive 1
Sub howRecursive (i As _Integer64)
If i < 0 Then Print "_Integer64 turned negative.": End
Print i
_Delay .000000000005
howRecursive i + 1
End Sub
Maybe with manual stack?
C++ Linker Flags: -Wl,--stack,134217728
Note, after changing the Compiler or Linker option flags, the first time you compile or run a program QB64 PE will rebuild runtime libraries, which can take a few minutes. It just says "Building .exe file..." https://www.facebook.com/share/p/17CKtMLKts/

Man what a blast from the past! I had forgotten all about this post and topic.
thanks for the reminder @pmackay
