hi,

in source code , there is a fuction call like this :  int a = func(param);

then I debug it with gdb , whein it stop at this line,I want to print
the func's retvalue, which results  in a gdb sigtrap,and

cause gdb to go into a trap,  then I can not find where am I .

I konw there is a command to prevent gdb going to trap  like  this,
what is  that command?

thanks!
