To be on the safe side, can you verify that I did not misspell the
environment variable? I.e., is there a trailing underscore?
Note that the error in sageinspect is due to the fact that I also had
#11768 applied, which needs work. I don't know if the crash in
graph_generators is related.
Is that good or bad?
* It is good, since the xalloc version of Singular works very well, and
the crashes we discussed here have apparently been fixed upstream (and the
fixes backported). Hence, I am now going to finalise the spkg for review.
* It is bad, since I think we had hoped that we see easy-to-analyse
crashes in garbage collection - after all, I am using sage-5.5.rc0, which
has some of the weak reference patches applied. But if there is no crash,
there is nothing to analyse.
However, if I recall correctly, the crashes did only occur when also
considering #12215, not only #715 and #11521.
