alternative-intelligence-cp/aria: v0.7.0 — Wild Memory Improvements

Wild Memory Improvements

Per-Allocation Size Tracking

• Hidden WildHeader (magic + alloc_size) before each allocation
• aria_alloc_get_size() reads the allocation size from the header
• Accurate aria_free/aria_realloc size accounting — no more imprecise stats

Guard Pages (--guard-pages)

• mmap(PROT_NONE) sentinel pages placed before and after wild allocations
• Buffer overflows/underflows trigger SIGSEGV immediately
• Magic LSB distinguishes guard-page vs malloc mode at free time
• Linux only

Wild Stats Dashboard (--wild-stats)

• Formatted statistics box printed at program exit
• Shows current/peak usage, active allocs, total frees, leak count, WildX stats, quota
• Uses __attribute__((destructor)) for reliable atexit printing
• Injected into main() via LLVM IR during compilation

Bug Fix

• Fixed HEADER_MAGIC LSB bug: magic 0xA01A...BEEF had LSB=1, which broke the guard-page LSB masking in aria_free validation (frees were silently skipped). Changed to 0xA01A707000BEE0 (LSB=0).

Tests

• New tests/wild_stress_v070.aria: 9 tests (rapid alloc/free, concurrent, interleaved, realloc grow/shrink, large/small allocations, aria_alloc_get_size)
• All 6 existing test suites pass (regression clean)

Notes

• Arena, Pool, and Slab allocators already existed from prior work — not new in this release
