Project:      GNU Smalltalk

An infinite loop will crash the VM.

Simple Example:

address@hidden:~$ gst
GNU Smalltalk ready

st> Object subclass: Foo [ Foo class >> new [ ^ self new ] ]
st> Foo new
"Global garbage collection... done"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... done, heap grown"
"Global garbage collection... Segmentation fault (core dumped)



It would be convenient if gst could perform a maximum recursion check
(similar to python) on invoking a CompiledMethod, and signal an
Exception if the
(configurable) maximum recursion depth is reached or exceeded.
