包含Psychtoolbox函数的程序在接收到触发输入（每秒大约3个触发）后运行30分钟后崩溃，但在未连接任何触发时运行90分钟。程序中的所有数组似乎都不比分配的内存大。目前尚不清楚为什么该程序在30分钟后始终崩溃。
这是使用Psychtoolbox-3和Matlab 2018b在Lenovo Thinkpad上运行的。我们无法从matlab崩溃报告中破译来源（已经发布了类似的崩溃报告，但是所有发布都不适用于我们的错误）。 Matlab支持团队声称这不是Matlab错误，并且该错误表明使用Psychtoolbox出错。整个崩溃报告发布在下面。
---编辑-与接收触发有关的代码部分 注意-触发器将以“ =”键的形式接收，而主题在我们执行任务期间所按的按钮将以“ 1”和“ 2”的
形式接收KB_task=i(find(strcmp(j,'Keyboard'))); %selecting the keyboard named keyboard
KbQueueCreate(KB_task); %setting up queues to track keypresses
KBQueueStart(KB_task);
%check for press (we check approx. every .0167 s)
[pressed,firstpress]=KbQueueCheck(KB_task);
%saving out the time and identity of the button press
if pressed
k=find(firstpress);
for j=1:length(k)
keyval(indx)=k(j);
trtimes(indx)=firstpress(k(j));
indx=indx+1;
end
