I stumbled upon the same problem as http://savannah.gnu.org/bugs/?35367 . It affects only some architectures (32-bit i686, 64-bit s390x and PPC). Disabling FMA (%configure CFLAGS="$CFLAGS -ffp-contract=off") does not help. Does this error indicate a serious bug/miscompilation or just an equation too difficult for the solver?

Subsequent error handling is also strange. Is GSL really supposed to call abort() and kill any unsuspecting caller without warning?

I would love to help with debugging.
