Hi ironpython,

Here's your Daily Digest of new issues for project "IronPython".

In today's digest:ISSUES

1. [New issue] StackOverflow with continue from try..except



1. [New issue] StackOverflow with continue from try..except
User shacktoms has proposed the issue:

"We are running IronPython 2.7.3. We have been getting a StackOverflow error, which we have reduced to the attached program. It only crashes when run under ipy64, without -X:Debug.

The crash is very easy to make go away, with seemingly innocuous modifications to the program, and different builds of IronPython 2.7.2 (e.g. a debug build) produce different behavior and the program will need some modification in order to exhibit the crash. I have never seen the problem with ipy.exe, only with ipy64.exe.

But if I put this program, excon1.py, in my C:\Program Files (x86)\IronPython 2.7 folder, start a command prompt in that folder and type
ipy64 excon1.py

I see...
Process is terminated due to StackOverflowException.

It doesn't go very far before overflowing the stack. On my machine I can reduce the range(1000) to range(50) and still see the crash.

def f(j):
    raise Exception("test")

for j in range(1000):
print "finished"
