Unimplemented Opcode (00 EB 0D 90) 64 86 8B 30 03 00 00 80 F9 02 75 2E 64 0F B6 While trying to run darwinia 10k (darwinia 10000th anniversary version) i ran into this problem. In fact, the common log just says this: ``` Rename process to "darwinia" Redirecting overridden malloc from symtab function for /storage/roms/ports/darwinia10k/darwinia Using native(wrapped) libdl.so.2 Using native(wrapped) libm.so.6 Using emulated /roms/ports/darwinia10k/libs/libsentry.so Using emulated /roms/ports/darwinia10k/box64/x64/libstdc++.so.6 Using emulated /roms/ports/darwinia10k/box64/x64/libgcc_s.so.1 Using native(wrapped) libpthread.so.0 Using native(wrapped) libc.so.6 Using native(wrapped) ld-linux-x86-64.so.2 Using native(wrapped) libutil.so.1 Using native(wrapped) librt.so.1 Using emulated /roms/ports/darwinia10k/libs/libcurl.so Using native(wrapped) libz.so.1 Using emulated /roms/ports/darwinia10k/libs/libssl.so.1.1 Using emulated /roms/ports/darwinia10k/libs/libcrypto.so.1.1 Warning: Global Symbol ZSTD_trace_decompress_begin not found, cannot apply R_X86_64_GLOB_DAT @0x10075bb98 ((nil)) in /storage/roms/ports/darwinia10k/darwinia Warning: Global Symbol ZSTD_trace_decompress_end not found, cannot apply R_X86_64_GLOB_DAT @0x10075bba0 ((nil)) in /storage/roms/ports/darwinia10k/darwinia 1896|0x1005ee000: Unimplemented Opcode (00 EB 0D 90) 64 86 8B 30 03 00 00 80 F9 02 75 2E 64 0F B6 ``` and i'm unsure whether the crash-on-start is caused by the libz missing simbols or the unimplemented opcode, but i'm guessing it's the opcode.
