[Swift-user] Fixed array vs array mapper

[Jonathan Ozik]

I'm having trouble using array mappers for output files. The fixed array mapper seems to work on 0.94.1 but not with trunk. I've put together a minimal case that will hopefully help shed light on the issue. There's a swift script and a simple bash script that creates files.
I've tried this both with 0.94.1 and with the trunk as of May 16.

Trying the array mapper:
With 0.94.1, the execution just hangs at:
*** Ready to call sum_obj

With the trunk version I get the error:
*** Ready to call sum_obj


Execution failed:

If I use the fixed array mapper, the 0.94.1 works but the trunk version gives:
*** Ready to call sum_obj

WARNING: duplicate mapping found:
	fs (line 18) and fs (line 18) are both used to write to file://localhost/

Any thoughts on what might be going wrong would be greatly appreciated!
