使用勘误表中给出的正确valgrind
版本,这似乎只适用于Valgrind 3.6.1。我的调用:

--trace-children=yes --peak-inaccuracy=0.5 --pages-as-heap=yes \
--massif-out-file=myProcesses".%p" ./testscript.sh

Massif 继续抱怨我其余文件中的堆分配。请注意,这与您的错误非常相似。
我推测您的版本valgrind
是在调试模式下构建的,导致断言触发。从源代码重建(我在默认情况下使用它./configure
)将解决这个问题。
无论哪种方式,这似乎都是 Massif 所期望的。
