--- Comment #20 from Leif Leonhardy <bugfeed at online dot de> 2012-04-09 16:42:38 UTC --- (In reply to comment #16) > It is time to do something as GCC 4.7 is quite hampered by this on IA-64. Indeed. Besides MPIR (hence presumably also GMP) and NTL, also MPFR, GMP-ECM, PARI, FLINT and some other less prominent packages fail to build due to this error (unless one specifies `-O0 ...`).
