Okay, thanks. I just had a quick look and it seems your #ifdefs are not quite
correct. In ppheap, you are using special alignment conditions when __sun
is defined. But the alignment issues do not generally affect Solaris but SPARC
machines only (Solaris runs on x86 as well).

So, I think the better approach would be to test for the definition of __sparc
which is the most generic definition that's available both on Linux/SPARC as well
as Solaris/SPARC.

On Linux:

glaubitz at kyoto:~$ echo | gcc -E -dM - |grep __sparc
#define __sparc__ 1
#define __sparc 1
#define __sparc_v9__ 1
glaubitz at kyoto:~$

On Solaris:

sysadmin at deimos:/opt/solarisstudio12.3/bin$ ./suncc -xdumpmacros -E /dev/null                      
#define __LINE__

sysadmin at deimos:/opt/solarisstudio12.3/bin$

@Hilmar:

If you patch texk/web2c/luatexdir/luapplib/{ppconf.h,ppheap.c,util/utilarm.h} to
replace "( defined(__sun) && defined(__SVR4))" with "defined __sparc", the problem
should be fixed on Debian sparc64.
