Comment (by zimmerma):
I tried configuring GMP-ECM with {{{-enable-assert}}}, nothing wrong
happens.
I have no further idea to investigate. Any suggestion out there?
Of course a possible workaround would be to configure with {{{--disable-
asm-redc}}} on
powerpc64, but it would be nice to find the reason of this problem. Is
there any other
powerpc on which we could test?
What is strange is that the bug occurs **inside** libecm.a when called
from within Sage,
and does not occur when called from the binary GMP-ECM (with the same
libecm.a). Maybe a memory corruption related to the ecm_params structure
which is not really defined in libecm.pyx? Is it possible to link libecm
dynamically to Sage?
