 当您在gdb下运行程序时，与直接从shell运行它相比，执行将在几个方面有所不同： 
 
 
 
 默认情况下，gdb将禁用地址空间布局随机化（ASLR） ，以便在每次运行时为您提供更多可重现的结果。 但这可能会掩盖程序中的内存损坏错误。 您可以在启动程序之前键入(gdb) set disable-randomization off来禁用此功能。 
 
 
 gdb将在程序环境中设置LINES和COLUMNS ，如果它们不存在则创建它们。 这将改变环境的大小，因此当在gdb下运行时，程序堆栈的基础将是不同的。 您可以在启动程序之前键入(gdb) unset environment COLUMNS和(gdb) unset environment LINES ，从(gdb) unset environment LINES删除这些变量。 
 
 
 gdb监视动态库事件和线程创建，在发生时暂时停止执行。 
 

When you run a program under gdb, the execution will differ in a few ways compared to running it directly from a shell:
 
 
 
gdb will, by default, disable Address Space Layout Randomization (ASLR) in order to give you more reproducible results on each run. But this may mask memory corruption errors in your program. You can disable this feature by typing (gdb) set disable-randomization off before starting your program.
 
 
gdb will set LINES and COLUMNS in your program's environment, creating them if they were not present. This will alter the size of the environment, thus the base of the stack of the program will be different when run under gdb. You can remove those variables from the environment by typing (gdb) unset environment COLUMNS and (gdb) unset environment LINES before starting your program.
 
 
gdb monitors dynamic library events and thread creation, briefly stopping execution when they occur.
