This one is caused by a [GCC regression](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116057) and affects arm64 as well.\n- [x] (v24.x)  https://github.com/nodejs/node/issues/60895 https://github.com/riscv-forks/electron/issues/9. Should be fixed by ~~https://github.com/nodejs/node/pull/58746~~ https://github.com/nodejs/node/pull/60962\n- [ ] https://github.com/riscv-forks/electron/issues/7. This one also appears to be a GCC specific bug as node compiled with clang is not affected.\n- [x] (v22.x, v23.x) https://github.com/riscv-forks/electron/issues/6. Fixed by https://github.com/nodejs/node/pull/56781\n- [ ] (all versions after v20.x) https://github.com/riscv-forks/electron/issues/3. WebAssembly's trap handler implementation uses a lot of virtual memory for guard pages, where risc-v systems with `Sv39` only have 256GB virtual memory and would quickly run out of address space when multiple wasm are running.\n  - [ ] Disabling trap handler would solve it but also leads to other new bugs like https://github.com/riscv-forks/electron/issues/8 \n- [x] (all versions from at least v16.x) https://github.com/revyos/revyos/issues/27. This one only triggers on SG2042, which has 64 cores. It is mysterious as it happens by chance and when gdb is attached, the call stack is already corrupted so the cause is still unknown.\n  - This one also appears to affect loongarch64. (fixed in https://chromium-review.googlesource.com/c/v8/v8/+/6786372)\n  - Should be fixed with https://github.com/nodejs/node/pull/61666\n- [ ] [Node.js test-snapshot-reproducible.js failing on riscv64](https://issues.chromium.org/issues/460332153) \n# Performance Regressions\n\n- [x] (v21.x, v22.x) https://github.com/riscv-forks/electron/issues/1.
