Got a core dump this evening from this evenings GIT build. On a Fedora 12 machine (I know, horbly obsolete), on a Centrino M CPU:

Curiously enough, on Ubuntu 12.04 on *exactly the same hardware*, I don't have this problem, even with this evening's build. -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
