The documentation (https://github.com/ethereum/wiki/wiki/Subtleties) states that SUICIDE becomes effective at the end of the transaction, but in block 116525, the same contract was able to SUICIDE three times in three distinct transactions:

0x7476afface26678a6c236618a7079db7ce567a213dc75652378f3580e1a10f28
0x51826f28e829cb9425dbd1c77a2c77484d04d8b02ccab05934e5885d313fbe91
0xa6c23583bba9139ca7e168328a2d15978d90dfdd61a6be697abbec1846b59e01

is it a bug that has since been fixed, or is a SUICIDE only effective after a block is complete?

  • why do you say suicide has been called 3 times ? I see it only happening in the 1st you mention but can be wrong of course – euri10 May 10 '16 at 15:13
  • ethercamp explorer and debug_traceTransaction report it for all 3 transactions (could be a bug in both of these though) – fair glu May 10 '16 at 18:51
  • I only see it showing up once on ethercamp. – Tjaden Hess♦ May 10 '16 at 22:26
  • What version of geth are you using? I get the bug on 1.5.0, do you see it on 1.4.3? – Tjaden Hess♦ May 10 '16 at 22:43
  • I am on 1.5.0 from ppa:ethereum/ethereum-dev, I cannot see it in ethercamp anymore, must have gotten confused at some point :/ – fair glu May 11 '16 at 6:22

A SUICIDE operation is effective at the end of the transaction. I can replicate the issue, so it likely is a bug in the geth traceTransaction implementation, where the other prior transactions in the block are not taken into account.

Edit: this bug has been fixed

  • I submitted an issue feel free to chime in with your geth version, etc. – Tjaden Hess♦ May 10 '16 at 22:59

    Added a comment in issue #2542, and, yes, that is with 1.5.0 – fair glu May 11 '16 at 6:26
