fatal error crash while trying a second transaction from mining adress

[RobStof]

Describe the issue

fatal error crash while trying a second transaction from mining adress (in the same, or not the same block).

Can you reliably reproduce the issue?

Yes, each time I try to send a transaction after the first one.

If so, please list the steps to reproduce below:

1. Sending 1 G from my mining account to someones account, confirming, no problems.
2. Sending another 1 G from my mining account to someone elses account, confirming with code, error popup.
3. Getting fatal error.

What version of Gulden are you using?

latest .18 build (but problem was also present with the first sigma builds)

Machine specs:

• OS: win10 home
• CPU: i7 intel 7700HQ (kaby lake)
• RAM: 16gb ddr4
• Disk size: 256GB
• Disk Type (HD/SDD): SSD

Extra information:

• Stopping the mining process doesn't make any difference with the fatal error popping up.
• Tried to wait for the second transaction to find place in a new block, doesn't fix the error.
• The problem was also present in other sigma builds (I tried several times with the new builds).
