我知道很多人都遇到了这个问题，而且我也经历了很多。但是我仍然无法解决我的问题。就这个：
我的代码是c ++代码。但是我需要针对我的问题调用c语言编写的共享库（ODE求解器）。
int Reaction::cvodedensewrapper()
在此调用ODE求解器的功能。我的类是Response，而cvodedenseWrapper（）是类函数。我为从c ++到c的数据传输定义了一个结构：
typedef struct {
unsigned int exp_ID, nExp,nRec, nComp;
realtype *Ts;
realtype *dTs;
realtype *ts;
realtype *vkp;
realtype Tr;
} User;
typedef User *UserData;
在这里，实型是双精度型的名称。我在代码中定义了UserData类型变量，分配了内存并将其初始化为：
User data;
UserData udata=& data;
udata->Ts=new realtype[numExp];
udata->dTs=new realtype[numExp];
udata->ts=new realtype[numExp];
udata->vkp=new realtype[2*numRec];
udata->nExp=numExp;
udata->nRec=numRec;
udata->nComp=numComp;
udata->Tr=Tref;
for(i=0;i!=numExp;i++)
{
udata->Ts[i]=Tstart[i];
udata->dTs[i]=dT[i];
udata->ts[i]=tstart[i];
}
for(i=0;i!=2*numRec;i++)
{
udata->vkp[i]=vk[i];
}
udata将循环循环传递到ODE求解器六次。每次，我使用以下代码监视动态数组的地址及其内容：
printf("udata->Ts: %p\n",udata->Ts);
for(i=0;i!=numExp;i++)
printf(" Ts[%d]=%.5f ",i,udata->Ts[i]);
printf("\n");
printf("udata->dTs: %p\n",udata->dTs);
for(i=0;i!=numExp;i++)
printf(" dTs[%d]=%.5f ",i,udata->dTs[i]);
printf("\n");
printf("udata->ts: %p\n",udata->ts);
for(i=0;i!=numExp;i++)
printf(" ts[%d]=%.5f ",i,udata->ts[i]);
printf("\n");
printf("udata->vkp: %p\n",udata->vkp);
for(i=0;i!=2*numRec;i++)
printf(" vkp[%d]=%.5f ",i,udata->vkp[i]);
printf("\n");
第一次输出：
m = 0
udata->Ts: 0x62c430
Ts[0]=673.00000 Ts[1]=698.00000 Ts[2]=723.00000 Ts[3]=748.00000 Ts[4]=773.00000 Ts[5]=798.00000
udata->dTs: 0x638f30
dTs[0]=0.00000 dTs[1]=0.00000 dTs[2]=0.00000 dTs[3]=0.00000 dTs[4]=0.00000 dTs[5]=0.00000
udata->ts: 0x638f70
ts[0]=316.09846 ts[1]=283.41932 ts[2]=253.00015 ts[3]=224.61435 ts[4]=198.06463 ts[5]=173.17842
udata->vkp: 0x62e150
vkp[0]=-4.22868 vkp[1]=-2.73312 vkp[2]=2.80980 vkp[3]=-1.65961 vkp[4]=27.23419 vkp[5]=25.96871vkp[6]=16.03558 vkp[7]=10.69316
作为比较，这是第六个输出，
udata->Ts: 0x62c430
Ts[0]=673.00000 Ts[1]=698.00000 Ts[2]=723.00000 Ts[3]=748.00000 Ts[4]=773.00000 Ts[5]=798.00000
udata->dTs: 0x638f30
dTs[0]=0.00000 dTs[1]=0.00000 dTs[2]=0.00000 dTs[3]=0.00000 dTs[4]=0.00000 dTs[5]=0.00000
udata->ts: 0x638f70
ts[0]=316.09846 ts[1]=283.41932 ts[2]=253.00015 ts[3]=224.61435 ts[4]=198.06463 ts[5]=173.17842
udata->vkp: 0x62e150
vkp[0]=-4.22868 vkp[1]=-2.73312 vkp[2]=2.80980 vkp[3]=-1.65961 vkp[4]=27.23419 vkp[5]=25.96871vkp[6]=16.03558 vkp[7]=10.69316
循环之后，我仅使用以下语法释放内存，
delete [] udata->Ts;
delete [] udata->dTs;
delete [] udata->ts;
delete [] udata->vkp;
udata=NULL;
可以看到指针和内容指针指向的保持不变。没有改变。因此排除了其他遇到的问题。这是我唯一使用delete的地方。

最佳答案
您的问题几乎可以肯定是未显示的代码。
根据CVodeSetUserData的documentation，它只是将UserData传递给求解器最终将调用的函数（在这种情况下为f）。
无论如何，可以直接指出错误的工具是Valgrind。只需在其下运行程序，它将准确告诉您如何破坏堆。
