Perhaps we could try a combination of the two, to ensure that no script is terminated due to a PHP crash if allocating on the stack fails. By default we can use alloca() if that fails to allocate the memory, we could use emalloc() and set a flag free code indicating which free function should be used.
I'm hesitant to slow down the general case (even if it's just an additional if()) statement. I'd revert to alloca() and we can always add a --paranoid-stack-allocation directive to configure to use emalloc() :)
