Hi all
texmacs (www.texmacs.org) is a free wysiwyw (what you see is what you want)
editor which depends on guile-1.8-libs. Debian currently has guile
1.8.2+1-2. The previous guile version was 1.8.1+1-5.
If texmacs is compiled on a machine with guile 1.8.2+1-2 libraries and is
installed on a machine using 1.8.1+1-5 then executing texmacs is giving the
following error
texmacs.bin: Symbol `scm_i_freelist' has different size in shared
object, consider re-linking
TeXmacs] With linked TrueType support
Segmentation fault
More information about this issue can be found at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=439923 . Can someone give
me an idea where the mistake is? Since .so version has not changed between
1.8.1 and 1.8.2, I am assuming we can mix them. Is that correct or am I
completely off the track? If it is a bug, it would be great to see a fix
for it by guile 1.8.3.
thanks in advance for any suggestions/pointers/comments...

G-Wrap also has been bitten by that; from the guile-1.8 changelog.Debian:
guile-1.8 (1.8.2+1-2) unstable; urgency=low
* Re-enable threads.

Apparently, enabling thread support changes the ABI; to verify this is
indeed the problem, try texmacs together with guile-1.8 1.8.2+1-1 - if
I'm correct, that should fix the segfault. Then just rebuild with the
latest guile-1.8 to fix the problem.

If texmacs is compiled with guile 1.8.2+1-1, and run on a machine having
guile 1.8.2+1-1 then there are no problems. The problem arises only if
there is a mix of guile versions. Does change in ABI count as a bug?

If there isn't a change in the SONAME, too: Yes, IMO.
