So, no, not really fixed although it sometimes seems so. Some examples in chronological order: As root: # cpufetch Name: Intel Core i7 920 Microarchitecture: Nehalem Technology: 45nm Max Frequency: Unknown Cores: 1 cores (HT disabled) AVX: No FMA: No L1i Size: 32KB L1d Size: 32KB L2 Size: 256KB L3 Size: 8MB Peak Performance: Unknown # cpufetch --style legacy Floating point exception # cpufetch --style legacy ###@ ##@##@ ###@ ###@ ##@ ###@Name: Intel Core i7 920 ##@ ##@ Microarchitecture: Nehalem ##@ ##@ Technology: 45nm @##@##@##@ Max Frequency: Unknown #@ ##@ @ #@ #@##@##@ Cores: 1 cores (HT disabled) #@##@ ##@##@ ##@###@ ###@ ##@##@ AVX: No #@ ##@ ##@##@ ##@##@##@ ##@ ##@ FMA: No #@ ##@ ##@##@ ##@#@ ##@ ###@L1i Size: 32KB #@ ##@ ##@##@ ##@##@ ##@ @ L1d Size: 32KB #@ #@ ##@##@ @ @ #@ ##@L2 Size: 256KB ##@ L3 Size: 8MB ##@ Peak Performance: Unknown ###@###@ @ #@ #@ ###@ ##@ # As user: $ cpufetch [1]31108 floating point exception cpufetch $ cpufetch Name: Intel Core i7 920 Microarchitecture: Nehalem Technology: 45nm Max Frequency: Unknown Cores: 1 cores (HT disabled) AVX: No FMA: No L1i Size: 32KB L1d Size: 32KB L2 Size: 256KB L3 Size: 8MB Peak

Bug#999588: cpufetch: Floating point exception

bug report on) running Debian Testing, I get the following error when
