Fix: critical malloc size calculation bug 2026-01-02T18:13:08Z Richard Qin richard.qin.x@gmail.com 2026-01-02T18:13:08Z urn:sha1:10614e04929a6d109a5e90524e446b637aaf0c13 Summary: - Fixed an integer arithmetic error in malloc() where 'nunits' was initialized to 0, causing incorrect heap sizing. - This bug caused malloc to return pointers pointing to unmapped memory pages, leading to Store Page Fault (scause 15) at process boundaries. - Switched memory allocator logic to use byte-based size calculation instead of K&R style units to prevent off-by-one errors. Improvements: - Shell now starts successfully without segfaults. dev(sell): add simple libc and implement shell 2026-01-02T02:09:37Z Richard Qin richard.qin.x@gmail.com 2026-01-02T02:09:37Z urn:sha1:1c8e37f63d413a559825020289178d442537449e please see the log for detail.
