Debugging crashes reported by abrt


  • Signal 5 (SIGTRAP) = “General crash”
  • Signal 6 (SIGABRT) = SIGABRT is commonly used by libc and other libraries to abort the program in case of critical errors. For example, glibc sends an SIGABRT in case of a detected double-free or other heap corruptions.
  • Signal 11 (SIGSEGV) = Segmentation fault, bus error, or access violation. It is generally an attempt to access memory that the CPU cannot physically address.
