Description Miguel de Icaza 2009-05-10 18:42:53 UTC

Created attachment 291204 [details]
The tail call test that is failing.

The following F# program tests a number of tail call features in the runtime and is currently failing in Mono.

To reproduce:
1. Download the zip file for F# September 2008 Community Release from:
http://www.microsoft.com/downloads/details.aspx?FamilyID=61ad6924-93ad-48dc-8c67-60f7e7803d3c&displaylang=en

2. Unzip fsharp.zip

3. cd FSharp-1.9.6.2

4. sh install-mono.sh

5. Compile the sample:
mono bin/fsc.exe TailCallsTest.cs

6. Run, it should complete.   Currently we terminate with a stack overflow:

simpleTail1: YES
simpleTail2: YES
mutualTail1IsOdd: YES
mutualTail1IsEven: YES
Stack overflow in unmanaged: IP: 0x7f8572a2ad8b, fault addr: 0x7fff7b6d4cd8
Stack overflow: IP: 0x58f926, fault addr: 0x7fff7b6c6398
At Unmanaged
