<!-- This issue tracker is only for technical issues related to Bitcoin Core.

General bitcoin questions and/or support requests are best directed to the Bitcoin StackExchange at https://bitcoin.stackexchange.com.

For reporting security issues, please read instructions at https://bitcoincore.org/en/contact/.

If the node is "stuck" during sync or giving "block checksum mismatch" errors, please ensure your hardware is stable by running memtest and observe CPU temperature with a load-test tool such as linpack before creating an issue! -->

<!-- Describe the issue -->

Bitcoind takes up 100% cpu, log file not written to. Even bitcoind --help isn't working.

**Expected behavior**

Run normally
<!--- What behavior did you expect? -->

**Actual behavior**

100% cpu usage, no output
<!--- What was the actual behavior (provide screenshots if the issue is GUI-related)? -->

**To reproduce**

Compile current master and try to run bitcoind
<!--- How reliably can you reproduce the issue, what are the steps to do so? -->


**System information**

<!-- What version of Bitcoin Core are you using, where did you get it (website, self-compiled, etc)? -->
latest master
<!-- What type of machine are you observing the error on (OS/CPU and disk type)? -->
Debian Buster
VM with 28 Xeon Platinum cores, 64GB RAM, SSD storage

<!-- GUI-related issue? What is your operating system and its version? If Linux, what is your desktop environment and graphical shell? -->

<!-- Any extra information that might be useful in the debugging process. -->
<!--- This is normally the contents of a `debug.log` or `config.log` file. Raw text or a link to a pastebin type site are preferred. -->

Compiled  from  v0.19.0.1 tag and it's working.
