[PATCH] Avoid out of scope access in hsa-dump.c

[Bernd Edlinger]

Hi,

this fixes an use of a buffer after the block scope
in hsa-dump.c: "buf" is assigned to "name" and used after
the scope ends in a fprintf.

I have not done any real checks, except boot-strapping with
all languages.
Is it OK for trunk?


Thanks
Bernd.
