代码定位

 oceanbase::sql::ObSQLParser sql_parser(*(oceanbase::common::ObIAllocator *)(parse_result.malloc_pool_),
                           parse_result.sql_mode_);
      if (OB_FAIL(sql_parser.parse(ob.ptr(),  ob.length(), parse_result))) {
        PROXY_LOG(WARN, "failed to do obparse",K(ob), K(sql_string), K(ret));
      } else {
        PROXY_LOG(DEBUG, "obparse succ", K(sql_string), K(ret));
      }
    }

错误发生在sql_parser.parse方法中，看了下是个对应的.a文件，然后在oceanbase侧查找对应代码
oceanbase代码

int ObSQLParser::parse(const char * str_ptr, const int64_t str_len, ParseResult &result)
{
  int ret = OB_SUCCESS;
#ifndef SQL_PARSER_COMPILATION
  // proxy don't need this, only for observer
  ObActiveSessionGuard::get_stat().in_parse_ = true;
#endif
  if (0 != parse_init(&result)) {
    ret = OB_ERR_PARSER_INIT;
  } else {
    ret = parse_sql(&result, str_ptr, static_cast<size_t>(str_len));
  }```
应该是初始化错误导致的，然后再往里看

int parse_init(ParseResult *p)
{
int ret = 0; // can not include C++ file “ob_define.h”
static thread char error_msg[MAX_ERROR_MSG] = {’\0’};
p->error_msg = error_msg;
if (OB_UNLIKELY(NULL == p || NULL == p->malloc_pool)) {
ret = -1;
if (NULL != p) {
(void)snprintf(p->error_msg_, MAX_ERROR_MSG, “malloc_pool_ must be set”);
}
}

if (OB_LIKELY( 0 == ret)) {
ret = obsql_mysql_yylex_init_extra(p, &(p->yyscan_info_));
}
return ret;
}

排除p->malloc_pool_的情况，对应方法obsql_mysql_yylex_init_extra是个yacc部分代码，这部分如何排查或者debug.或者我排查的逻辑是否存在问题，应该是什么问题导致的

yacc 也是代码，可以直接对着代码看，跟C++类似的。
