Re: Kudzu segmentation fault. Core5 Test3 upto date as of March 4, 2006

I am suffering the same problem with seg faults using kudzu. My system is a Dell Inspiron 8000 (PIII 700 Mhz laptop). 'kudzu -s' does not cause a seg fault. I can file a bug if the other gentleman has not already done so and add this information along with whatever else you need.

Same problems here. My hardware: HP Pavilion zt3010us (P4 1.5 GHz Centrino laptop).

kudzu -s doesn't segfault, but kudzu does.

I've ran a strace kudzu and the latest things are:
