Hello Benjamin,

Indeed, it was after a "make ptestlong" or something similar. And it reproduced on both sage-6.7.beta0 and sage-6.7.beta1.

The error is very strange since it corresponds to a test of some return type. I will try to get something more verbose. And there is no caching involved as far as I can tell...

Hi Vincent,

well, at least I'm not the only one. For now, I don't really have a clue
regarding where this could come from.
I'm still compiling a clean version of 6.7.beta1, but now I guess that
won't change much.

The circumstance that this error only seems to appear after a series of
doctests (I suppose you ran "make
ptestlong" too?) confuses me. Could this point towards something like
caching or memory leak?
