<br>
I see from the log file that the crash happens when the C2 CompilerThread is doing a native clock_gettime/__vdso_clock_gettime. <br>
So I wonder whether this is a problem that is QEMU-specific? Does it trigger on hardware platforms like Unmatched board? <br>
Also did you try the pre-built JDK binaries for RISCV64 here at [1]? <br>
