Panic occurred when using nested pools #86

Closed coolcode-ws closed 4 years ago

coolcode-ws commented 4 years ago

call chain :

pool1:
    antsP, _ := ants.NewPoolWithFunc(len(block.GetTransactions()), func(params interface{}) {
        syncVerify1(params) //handle some verify, this func define another ants pool
        xxxx
    })
    defer antsP.Release()
pool2:
      syncVerify1(params{
            xxxx
           antsP1, _ := ants.NewPoolWithFunc(len(block.GetTransactions()), func(params interface{}) {
        syncVerify2(params)
        xxx
    })
    defer antsP1.Release()//problems happens
      }

You should fill out the template of the bug report, now you just erase it and add your info, which puts me in the position of not knowing anything about your local environment.

I don't even know what OS you were running on, what version of ants you were using, etc.
