核心转储,但是找不到错误位置,有GDB的错误信息
core dumped,but I don't find the error location,there have the GDB's error infomation

不叫我的代码。首先,我认为它是由3rdParty库调用的,并且该方法存在于3rdParty的源代码中;但是当我搜索utf8Helper
密钥时,我没有发现它被使用过。所以我不知道原因,你能帮帮我吗?
@MatthewFisher hm。我在doLoadFromCommonData上设置了一个断点,但它不起作用,程序没有加入它。我使用' export MALLOC_CHECK_=2 '和' ./test ',它生成一个core.4675。使用"gdb ./test core"。4675 ',' where '产生了一个段落:
