      # JRE version: OpenJDK Runtime Environment Corretto-25.0.1.8.1 (25.0.1+8) (build 25.0.1+8-LTS)
      # Java VM: OpenJDK 64-Bit Server VM Corretto-25.0.1.8.1 (25.0.1+8-LTS, mixed mode, tiered, compressed oops, compressed class ptrs, shenandoah gc, linux-amd64)



      A DESCRIPTION OF THE PROBLEM :
      I experienced a handful of SIGSEGV crashes when testing out GenShen on JDK25:

      # V [libjvm.so+0xf7a623] ShenandoahMark::mark_loop(unsigned int, TaskTerminator*, ShenandoahReferenceProcessor*, ShenandoahGenerationType, bool, StringDedupMode, StringDedup::Requests*)+0x3c53


      I saw a few crashes on two different services of ours (but which share a lot of code) after testing. We only tried GenShen on a few services on staging stacks over a few days, so it's hard to say the impact - but frequency seems to be one segfault every 1-2 days.
