I don't know what to tell you, except the following is a *fact* with 32-bit Debian 5 (and other 32-bit Linuxes). (This doesn't happen on 64-bit Debian 5). 1. Build Sage without --enable-fat (for MPIR) and everything is fine; the full build completes and tests pass. 2. Build Sage with --enable-fat (for MPIR) and the compiler segfaults later when building Pari. > The bug may be triggered when building Pari against some version of > MPIR, but in this case it is far more likely the bug is elsewhere. > Certainly there is a bug in gcc irregardless, as compilers are not > supposed to segfault, no matter how broken the code is you are > compiling (unless you have some broken environment variables hanging > around). I agree that this is a bug in GCC, but unfortunately it is a bug in a lot of deployed GCC's, and we (=the Sage project) don't have the option of telling people to just "upgrade to GCC-4.4.2". Thanks for looking at this further (in your other messages). I just hope to find a workaround because at least once a week (maybe more) we specifically get complains from people about "Illegal Instruction" errors when they try to use Sage binaries. I'm trying GMP-4.3.1 with --enable-fat right now to see what happens. -- William --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "mpir-devel" group.
