This is an assert in the runtime:

Assert failure(PID 2520 [0x000009d8], Thread: 6004 [0x1774]): m_alignpad == 0

Maybe a dup of #70231, but doesn't look related to this exact test or to System.Text.Json.

@stephentoub stephentoub changed the title System.Text.Json.Tests crash with JsonReaderException m_alignpad = 0 assert failure Jun 19, 2022

Failed System.Text.Json.Tests in Rolling run 1833047 (6/19 AM)

  • 6/20 Core Dumps of System.Text.Json.Tests:
    • 8 failures (only 1 in Rolling) in last 7 days
    • 73 failures (only 1 in Rolling) in last 30 days (counts only failures with Core Dump)

We should analyze / disable ASAP as it impacts PRs quite heavily.

6/20 Core Dumps of System.Text.Json.Tests

Many other libraries tests hit this crash intermittently. See #70231 that is a duplicate.
