The problem was that a big record was allocated on the stack, which casued stack to run out. Fixed by using my_safe_alloca() instead of my_alloca() when allocating records. Now only records <= 16384 are allocated on the stack. mysql-test/r/stack-crash.result: Added test case mysql-test/t/stack-crash.test: Added test case storage/maria/ma_blockrec.c: Use my_safe_alloca() instead of my_alloca() storage/maria/ma_dynrec.c: Use my_safe_alloca() instead of my_alloca() storage/maria/maria_def.h: Added MARIA_MAX_RECORD_ON_STACK storage/maria/maria_pack.c: Use my_safe_alloca() instead of my_alloca()
