#5501: pickling high-precision intervals is broken
-----------------------+----------------------------------------------------
Reporter: boothby | Owner: jkantor
Type: defect | Status: new
Priority: critical | Milestone: sage-3.4.1
Component: numerical | Keywords:
-----------------------+----------------------------------------------------
Comment(by cwitty):
This is presumably due to these lines from mpfi_set_str, in mpfi_io.c (in
the MPFI library):
{{{
char tmp[1000];
/* bzero(tmp,1000); */
memset(tmp,0,1000);
slen= (int)strlen(s);
if(slen >=1000) return -1;
}}}
As a workaround, instead of passing the {{{RealIntervalFieldElement}}} x,
you could pass (x.parent(), x.lower(), x.upper()); then on the other side,
given (parent, lower, upper), reconstruct the original element with
parent(lower,upper).
