Created attachment 87447 [details] [PATCH] Fix for SIGSEGV in systemd-bootchart on short-living processes The function svg_ps_bars() dereferencess NULL pointer in the line endtime = ps->last->sampledata->sampletime; because of partially initialized ps_struct (ps->last == NULL). If some process terminates between scaning /proc directory in the log_sample() function and reading additional information from /proc/PID/... files, the files couldn't be read, the loop will be continued and partially initialized structure returned.
