Bug#618555: spatch: exception Failure("More that one variable in decl. Have to split to transform.")

[Jonathan Nieder <jrnieder@gmail.com>]

Package: coccinelle
Version: 0.2.4.deb-3

Hi,

Given the uninitialized.cocci and fast-import.c as below[1], we
find:

 $ spatch -sp_file uninitialized.cocci fast-import.c
 init_defs_builtins: /usr/share/coccinelle/standard.h
 HANDLING: fast-import.c
 Fatal error: exception Failure("More that one variable in decl. Have to split to transform.")

I see two problems:

 1. The message is unclear.  I suppose the intent is something like

	fatal: cannot transform a line with multiple declarations in it

 2. The limitation is unfortunate.

Known problem?  Do I understand correctly?

Thanks for spatch. :)  It's a great tool.
Jonathan
