Description
with Sage 4.8 I get:
sage: U.<x,y> = GF(2)[] sage: factor(x^6 + y^5 + x^5 + y^4,proof=False) /usr/local/sage-4.8-linux-64bit-ubuntu_10.04.3_lts-x86_64-Linux/local/lib/libcsage.so(print_backtrace+0x31)[0x2b670685e3a3] ... ------------------------------------------------------------------------ Unhandled SIGSEGV: A segmentation fault occurred in Sage. This probably occurred because a *compiled* component of Sage has a bug in it and is not properly wrapped with sig_on(), sig_off(). You might want to run Sage under gdb with 'sage -gdb' to debug this. Sage will now terminate. ------------------------------------------------------------------------ local/bin/sage-sage: line 303: 7365 Segmentation fault sage-ipython "$@" -i

fixed upstream. I asked if they plan a new release of Singular soon.

here is another test case which Seg. faults with Sage 5.0:
sage: U.<tt,xx> = GF(2)[] sage: factor(xx^6 + tt^5 + tt^4 + tt*xx^3,proof=False) ... Unhandled SIGSEGV: A segmentation fault occurred in Sage.
