F# crashes on Mono 2.10

Question

After reading some reports about the inadequacies of the Mono 2.6 garbage collector, I decided to give Mono 2.10 a go. I found that the 2.10 runtime crashes with the following simple F# program:

let rec f x acc =
  if x = 0 then acc
  else f (x - 1) (acc + 1)

f 10 0

Equivalent looping C# code runs just fine as does an F# hello world program. The F# code also works ok with Mono 2.6 and .Net. Can anyone else reproduce this? Is it a bug or is it just my installation?

Here are the various runtimes I've tried and results I got.

• Mono 2.10.2 (compiled from sources on Debian Squeeze)

  -- "Stack overflow: IP: 0x4153bb84, fault addr: (nil)"
  

• Mono 2.8 (compiled from sources on Debian Squeeze)

  -- "Native stacktrace: ..."
  

• Mono 2.10.2 (Windows binary)

  -- "mono.exe has stopped working" dialog.
  

• Mono 2.10.2 (VMware image)

  -- Segmentation fault
  

• Mono 2.6.7 (bundled with Debian Squeeze)

  -- Works fine
  

The F# compiler used was from the November 2010 CTP.
