只要malloc commonbackup的addressarray跟addressoffsetarray
程式執行就會出錯

我BCB6已經更新到SP4了
爬文爬了很久 原本以為是更新的問題 但是已更新也沒用
附上主程式 肯請解答 是否我的寫法有問題

附加檔案：4c52f010f0611_FIR_Generater.rar

malloc()完不是要配free()嗎?
感覺好像沒看到有free()......(漏看的話請見諒= =)

有 下面有一個bottom按了會free 我只有po運行的部份

換做 new 試試呢？？

bcb的幫助中有這樣的說明。

Description
The new operators offer dynamic storage allocation, similar but superior to the standard library function malloc.

請注意下面你打的程式碼

commonbackup[1]=(commonstruct *)malloc((arraywidth 1)*sizeof(commonstruct));

應該是 i 吧!
