Research direction

Start by examining the attached javadump.txt and the reported change from tracer 1.58.1 to 1.63.0 on Java 25 and 26 with Amazon Corretto. Investigate the profiling path, including why dd.profiling.ddprof.enabled=false does not prevent the crash, and compare behavior with the profiler fully disabled. Done means the crash is reproduced or explained and a regression test or verified fix prevents it.

Bug Report

We are seeing tengs of crashes per day across our fleet. Started happening after upgrading 1.58.1 to 1.63.0. We see it on both java 25 and 26.

We also tried setting dd.profiling.ddprof.enabled=false but it didnt fix the crashes. Fully disabling the profiler makes them go away though
