Hi there,
Thank you for your responses. Trying to isolate the problem, I'm now using
v8 outside webkit, i.e. through the 'v8shell' helper program,
I have discovered that v8 is working fine but when an incorrect expression
is given to the v8 shell, for instance a variable that does not exist, a
fault occurs and the v8shell process dies. The log trace is below.
Any idea?
many thanks
best
