**Problem**
While tracing the block with Parity tracer(`trace_block`) it returns
error for a few blocks.
<details><summary>Example of blocks that couldn't be traced</summary>
These are the example of payloads with the errors occured during tracing
the blocks:
1. `{"method":"trace_block","params":["0x24165bd"],"id":0}` - `first run
for txIndex 32 error: insufficient funds for gas * price + value:
address 0x000005D814d5abD6e0F9345c9b1f37C82Eaf1EBb have
547961731687102852 want 675024999764675175`
2. `{"method":"trace_block","params":["0x2658753"],"id":0}` - `first run
for txIndex 45 error: insufficient funds for gas * price + value:
address 0x000004BeDC012a5D043270AF67de24c20a3b8aeB have
211658993830905595 want 235579381558610848`
3. `{"method":"trace_block","params":["0x258b00c"],"id":0} -first run
for txIndex 274 error: insufficient funds for gas * price + value:
address 0xA3a762006D22806B35895f4C0599bAe3adF1B349 have
342048586356638524 want 386865441635818752`
</details>
After looking through the
[trace_filtering.go](https://github.com/ledgerwatch/erigon/blob/devel/cmd/rpcdaemon/commands/trace_filtering.go#L1006)
and
[trace_adhoc.go](https://github.com/ledgerwatch/erigon/blob/devel/cmd/rpcdaemon/commands/trace_adhoc.go#L1072)
noticed that `doCallMany` called with `gasBailOut = true` in
[one](https://github.com/ledgerwatch/erigon/blob/devel/cmd/rpcdaemon/commands/trace_adhoc.go#L1072)
place and `gasBailOut = false` in
[another](https://github.com/ledgerwatch/erigon/blob/devel/cmd/rpcdaemon/commands/trace_filtering.go#L1006)
(actually the part of the code that is called by `trace_block`.
Changing its value to `true` fixed the problem and traces are successful
with this change.
Attaching the partial result of the successful trace below.
