Package: libv8-2.2.24
Version: 2.2.24-5
Severity: normal
Tags: upstream
I accidentally wrote a javascript snipped with an errorious content;
though what I noticed was that nodejs suddenly segfaulted.
I've broken down the code to a snipped, that when ran manually in
nodejs shell (segtest.js) a segfault occurs. (havn't been able to pin
down a fully runnable file that will segfault)
Sometimes the last line has to be repeated some times for
the segfault to occur.
A full backtrace is also attached.
