Hi Andy,

The backtrace error of the message you answered is the 'corrupted double-linked
...'
which occurs 'rarely' and always gives a long output in the terminal + a
backtrace ...
;; -- the 2 errors might be [or are for sure] related, but...:
The 'gslice error' occurs 'all the time'. This tells me that they are not 'the
same'
and I still wish to try to debug. I have an idea:
1] here below is a 'full' backtrace [after installed guile-1.6-dev
nostrip...]
- may be it's better then the previous one? [for this error
GSlice I mean]
2] if not, as I have a full source tree ready to compile as many
times as I wish,
using libglib 2.22.4-1 and 2.18.9-2:
-] I could temporarily change the source code, with your
help, to open
a log and write in it these info you need
what do you think?
> Try valgrind perhaps?
I tried, but so far without much success: without help I am not sure I will
achieve any
useful result, and I have a feeling it would be quicker to temporarily change
the source
code, would it not be?
Thanks,
David
