| * | Fix: critical malloc size calculation bug | Richard Qin | 2026-01-03 | 1 | -1/+2 |
| | | | | | | | | | | | 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. | ||||
