Error: Failed to fit all segments into specified ranges.

大家好，

     我现在编译时总是遇到这个错误：

Error[e104]: Failed to fit all segments into specified ranges. Problem discovered in segment XDATA_N. Unable to place 2 block(s) (0x802 byte(s) total) in 0x29b byte(s) of memory. The problem occurred while processing the segment placement command "-P(XDATA)XDATA_N=_XDATA_START-_XDATA_END", where at the moment of placement the available memory ranges were "XDATA:1c65-1eff"

我的程序：

switch(t2_state){
case T2ST_IDLE:
     break;
case T2ST_GPRS_ON:
     execute_gop((struct GOP_ITEM*)gprs_on,sizeof(gprs_on)/sizeof(struct GOP_ITEM));                     //第一个execute_gop
     t2_state = T2ST_IDLE;
     break;
case T2ST_GPS_GET:
      execute_gop((struct GOP_ITEM*)gps_get_info,sizeof(gps_get_info)/sizeof(struct GOP_ITEM));  //第二个execute_gop
      t2_state = T2ST_IDLE;
     break;

如果我把第二execute_gop注释掉，编译就能通过。看起来是XDATA空间不足的问题，但是改变INT_HEAP_LEN的值似乎无影响。怎么办呢？被这个问题卡了3天了。请大家指点迷津，多谢了

您将INT_HEAP_LEN改小到1000或者更小试试
