It may cause even more fallout, see src/external/gpl3/gcc.old/dist/gcc/tree-ssa-ccp.c #if defined(__NetBSD__) && defined(NETBSD_NATIVE) /* * This is a big, ugly, temporary hack: * http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59958 * To make sure we have configured all our targets correctly, mimic the * #ifdef cascade from src/lib/libc/stdlib/jemalloc.c here and compile * time assert that the value matches gcc's MALLOC_ABI_ALIGNMENT here. */ #if defined(__alpha__) || defined(__amd64__) || defined(__sparc64__) \ || (defined(__arm__) && defined(__ARM_EABI__)) \ || defined(__ia64__) || defined(__powerpc__) \ || ((defined(__mips__) || defined(__riscv__)) && defined(_LP64)) #define JEMALLOC_TINY_MIN_2POW 3 #endif So the only "fix" is fixing the malloc override IMHO.
