+## 10_powerpc_crash_fix.dpatch by Ian Jackson <[EMAIL PROTECTED]>
+##
+## * Fix coredumping bug on ppc: Ubuntu bugzilla:
+## http://bugzilla.ubuntu.com/show_bug.cgi?id=13771
+## This is the same issue as
+## http://bugs.ghostscript.com/show_bug.cgi?id=687643
+## http://bugs.ghostscript.com/show_bug.cgi?id=687730
+## discussed in
+##
http://ghostscript.com/pipermail/gs-code-review/2004-September/004649.html
+## and probably the same as Debian bug #324796 and perhaps others in
+## Debian's gs-esp.
+##
+## This bug is due to gs's incorrect assumption that (where ref is an
+## important struct inside gs) sizeof(ref) % alignof(jmp_buf) == 0. This
+## is not true on ppc and apparently not necessarily on Itanium either.
+##
+## The `fix' I have applied is to wrap setjmp/longjmp up in macros which
+## arrange for jmp_buf to have alignment 1, as sketched out in the URLs
+## above. A previous attempt to fix it by padding ref out to the
+## alignment of jmp_buf failed and I don't know why; but I suspect other
+## unjustified assumptions in gs.
+##
+## GhostScript's algorithms ought to be repaired not to assume
+## falsehoods.
+##
