Created an attachment (id=11759)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=11759&action=view)
Testcase
Output of testcase:
Before foo:
a(1)=abc def ghij
a(2)=klm nop qrst
b(1)=abc def ghij
b(2)=klm nop qrst
In foo: c(1)=f ghi
After foo:
a(1)=abc d
a(2)=klm n
b(1)=abc d
b(2)=klm n
Bug: array a corrupted in subroutine call!
Bug: array b corrupted in subroutine call!

As I said to you in my email, this represents a new problem, which is exposed
