Hi guys,

I wonder if someone could give me a hand to find out why a FFI calling I am doing is crashing. In OSX it works correct but I am testing in CentOS and it fails. I wonder if it also crashes in other Linuxes too. 

I am using latest Pharo 5.0 with Spur. To reproduce:

1) Get latest Pharo 5.0 and Spur via:

wget -O- get.pharo.org/alpha+vm | bash

2) Inside Pharo, load my prototype tool:

Gofer it

package: 'OSSubprocess';

url: 'http://smalltalkhub.com/mc/marianopeck/OSSubprocess/main';

load.

3) This is the code I am executing and it's crashing:

| posixSpawnFileActionsT | posixSpawnFileActionsT := ExternalAddress allocate: 4.

If I change above line with this:

posixSpawnFileActionsT := ByteArray new: 4.

Then the function does not crash but it crashes in the future  posix_spawn_file_actions_destroy().
