Byron Foster commented on VELOCITY-682:
---------------------------------------

I've checked in a test case for this issue, offending line commented out.  Looks like \
RuntimeConstants.VM_PERM_INLINE_LOCAL needs to be true for this to fail.

> #evaluate breaks macro processing
> ---------------------------------
> 
> Key: VELOCITY-682
> URL: https://issues.apache.org/jira/browse/VELOCITY-682
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.6.1
> Reporter: Sergiu Dumitriu
> 
> When using #evaluate, all further macro processing is broken; old macros are not \
> recognized anymore, and new macros cannot be defined. For example:
> {noformat}
> #macro(aSimpleMacro)
> This is a simple macro
> #end
> ## called 3 times to show that it works each time
> #aSimpleMacro()
> #aSimpleMacro()
> #aSimpleMacro()
> #macro(doEval $b)
> #evaluate($x)
> #end
> #set($x = 'value of x')
> #doEval('$x')
> ## after the first call, which used an #evaluate, these two won't work anymore:
> #doEval('$x')
> #doEval('$x')
> #macro(anotherSimpleMacro)
> This is another simple macro
> #end
> ## This newly defined macro doesn't work, either...
> #anotherSimpleMacro()
> ## And the first macro, which worked well before, suddenly stops working
> #aSimpleMacro()
> {/noformat}
> should print:
> {noformat}
> This is a simple macro
> This is a simple macro
> This is a simple macro
> value of x
> value of x
> value of x
> This is another simple macro
> This is a simple macro
> {/noformat}
> but instead prints:
> {noformat}
> This is a simple macro
> This is a simple macro
> This is a simple macro
> value of x
> #doEval('$x')
> #doEval('$x')
> #anotherSimpleMacro()
> #aSimpleMacro()
> {/noformat}
