用mcmodel = medium [closed]编译时C程序崩溃

当使用mcmodel = medium编译时，C程序会因分段错误而崩溃 . 我们在堆栈上使用了一些非常大的数组，我们需要启用中型mcmodel . 我正在使用g 5.4，当我对应用程序进行扫描时，它会打印出错误 . 请告知如何调试 .

strace ./app 
execve("./app", ["./app"], [/* 65 vars */]) = -1 ENOMEM (Cannot allocate memory)
--- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=0} ---
+++ killed by SIGSEGV +++

粘贴可执行readelf -l app的readelf输出
