>Description:
The named service crashed with an assertion failure. The machine
is a mailserver running postfix-current. The messages are:
May 11 22:31:06 <daemon.crit> christel named[13876]:
/usr/src/lib/bind/isc/../../../contrib/bind9/lib/isc/mem.c:628:
INSIST(((unsigned char *)mem)[size] == 0xbe) failed
May 11 22:31:06 <daemon.crit> christel named[13876]: exiting
(due to assertion failure)
The failing function is (with the '->' pointing to the line in
question):
static inline void
mem_put(isc_mem_t *ctx, void *mem, size_t size) {
#if ISC_MEM_CHECKOVERRUN
-> INSIST(((unsigned char *)mem)[size] == 0xbe);
#endif
#if ISC_MEM_FILL
memset(mem, 0xde, size); /* Mnemonic for "dead". */
#else
UNUSED(size);
#endif
(ctx->memfree)(ctx->arg, mem);
}
