Question

今天,我面临一些类似情况。

*** glibc detected *** /usr/lib/R/bin/exec/R: double free or corruption (out): 0xb1f64430 ***

I am just wondering... that bit with XXX, at the end of my own methods, what is the DxEv? All of my own methods have either a D0Ev, D1Ev or D2Ev attached to them? Does this have any meaning?

And what about the 0x30 afterwards? Is that the number of bytes into my class? Or a function address? Could I resolve it somehow?

Answer 1

<代码>_XXXDXEv为单角功能名称——使用<代码>c++filt去除。

(_XXXDXEv+0x30) means that level of the backtrace was 48 bytes into the code for that function.

如果你有的话,则在gdb下重新开工,或者在核心档案中开挖。

Answer 2

该名称是所谓的人名(即由编篡人与争辩和返回类型分开)。您可使用<代码>c++filt,用于收回功能签名。 <代码>0x30从一开始即按批次并入功能代码流。
