Detail
======
Came across a random crash in Slapcode when testing it on OSX with Lasso 9.2.6. Essentially sourcefile collapses and Lasso dies.

This was fine in Lasso 9.2.3 — it's fairly major issue.

Some code to replicate the issue:

sourcefile(`with x in'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aa'sd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aa'sd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aa'sd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x i'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x ''aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aa'sd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aa'sd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aa'sd'`,`slapcode: slap`,true,false)
sourcefile(`with x in 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x in'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x i'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x 'aasd'`,`slapcode: slap`,true,false)
sourcefile(`with x ''aasd'`,`slapcode: slap`,true,false)

Actually, distilling it further it looks like this line maybe the culprit:

sourcefile(`with x in'aasd'`,`slapcode: slap`,false,false)

Yes, the code is invalid — but that's the point, it's being evaluted and any errors return back. This is rock solid on 9.2.3 OSX.

Suspect it's down to the new JIT compiler? or at the very least a change to compilation. Have not noticed as I've been running 9.2.3 locally.
