Comment 1 Stefan Dirsch 2005-06-09 14:41:16 UTC 
Hmm ... which platform? How to reproduce? Does xterm come up?
Comment 2 Andreas Schwab 2005-06-09 14:43:53 UTC 
Apparently ic->private.local.context is unaligned.
Comment 3 Andreas Schwab 2005-06-09 14:44:32 UTC 
Try samarium.
Comment 4 Matthias Hopf 2006-03-22 16:13:55 UTC 
Currently there are much more pressing issues. Reducing priority, but leaving assigned so it doesn't get lost.
Comment 5 Matthias Hopf 2006-08-16 15:32:54 UTC 
Hm - does this still happen?

struct _XicLocalPrivateRec:
+0   long value_mask   (64bit)
+8   DefTreeBase base  (4x64bit,8x32bit)
+72  DTIndex context   (32bit)

This was a pointer before, so this definitively changed with the Compose cache changes.

It was before:

struct _XicLocalPrivateRec:
+0   long value_mask   (64bit)
+8   DefTree *context  (64bit)

so I don't know how this could ever be unaligned...
I recently fixed an alignment issue, but hasn't been related to .context.

Closing as FIXED, please reopen if this is still an issue. Note that currently STABLE doesn't have any global compose caches yet (the code is there, but the caches aren't). You can force the creation and usage of personalized caches by mkdir .compose-cache in your home.
