[ragel-users] terminate called after throwing an instance of 'std::bad_alloc'

[Adrian Thurston]

Try using -T0. My guess is that the alphabet size is large and the 
allocation of tables is eating up too much memory.

To confirm you can run:

ragel -F -R -x sip_parser.rl > out.xml
rlgen-ruby out.xml

-Adrian
