Oracle VirtualBox 5.0.x – Segmentation Fault in PERL

Please see as well:

Yesterday and the day before I’ve exchanged several emails with Ana who downloaded our Hands-On-Lab from here:

• Hands On Lab
  Upgrade, Migrate, Consolidate to 12c

after OOW15, encountering a SEGMENTATION FAULT when trying to start the database upgrade with catctl.pl:

$ $ORACLE_HOME/perl/bin/perl catctl.pl catupgrd.sql

Segmentation fault 

Very strange thing … 

The database is in upgrade mode (checked this in the alert.log) and there are no strange things mentioned anywhere. Plus hundreds of people have run and completed our lab so far.

We checked several other things – and then I came across this tweet by Martin Klier yesterday:

and started to search a bit.

I have no 100% proof for the actual reason but several people seem to have issues with SEGMENTATION FAULTs in Oracle’s PERL ($ORACLE_HOME/perl/bin/perl) when using Oracle VirtualBox 5.0.x – and according to VitualBox Forum that seems to happen with the most recent VBox 5.0.10 as well.

The “funny” thing is that all works perfectly well in VBox 4.3.x …

It reminds me a lot on the reoccuring VBox bug with my German keyboard not allowing me to type in the | (pipe) character which requires to press “ALT GR” +  “<” keys together.
