I like to set up the conditional breakpoint in gdb such that gdb will break into “gdb>” only when the caller function of malloc() is not equal to my_mallc().

换句话说,当my_malloc未调用malloc时,您希望在malloc上中断.

一种方法是设置三个断点：一个在malloc上,一个在my_malloc上,一个在my_malloc上.然后(假设断点分别为1,2和3).

(gdb) commands 2
silent                # don't announce hitting breakpoint #2
disable 1             # don't stop when malloc is called within my_malloc
continue              # continue execution when BP#2 is hit
end

(gdb) commands 3
silent
enable 1              # re-enable malloc breakpoint
continue
end

此技术仅适用于单线程应用程序.
