Details:
This is a sample of Makefile:
.DELETE_ON_ERROR:
bug: c_foobar ;
c_%: a_% b_%
echo $^ > $@
b_%: a_%
echo $^ > $@
a_%:
false > $@
I tested it with make 3.81 on Ubuntu 12.04 LTS, make 4.0 on Ubuntu 14.04.1
LTS, and make 4.0 on Gentoo.
$ make
false > a_foobar
Makefile:13: recipe for target 'a_foobar' failed
make: *** [a_foobar] Error 1
$ make
echo a_foobar > b_foobar
echo a_foobar b_foobar > c_foobar
rm b_foobar

while when you specify a_foobar directly, it is deleted, as expected:
$ make a_foobar
false > a_foobar
Makefile:13: recipe for target 'a_foobar' failed
make: *** [a_foobar] Error 1
make: *** Deleting file 'a_foobar'
If you replace '%' in Makefile with 'foobar', everything works too, so it
seems to be pattern-related problem.
When you call pattern rule directly:
$ make c_foobar
false > a_foobar
Makefile:13: recipe for target 'a_foobar' failed
make: *** [a_foobar] Error 1
(not failing rule, but its parent), it also doesn't remove a_foobar, so it is
just pattern handling problem.
