Segmentation fault description explanation

When I got a segmentation fault like this:

sending SIGSEGV to MyProcess for invalid read access from (epc == 00000000, ra == 1aca1ed8)

What means the epc == 00000000 and ra == 1aca1ed8?

Can anyone explain it to me? Thanks.

  • epc is the Exception Program Counter, it should point to the address of the instruction that caused the exception.
  • ra is the Return Address register, it should point to the address to return from the function call.
