I'll do my best, but it might take me quite some time to get gdb set up with the symbols you mentioned. C++/debugging doesn't come naturally for me.
What it smells like to me is memory is being freed but then written to. Then when the system goes to allocate memory it says hey that memory isn't so free because it's still being written to (freed memory checksum mismatch).. And it isn't until the crime has been discovered at the time of m'allocation that an exception is thrown. Correct me if I'm wrong but the real problem (leak?) would be some to many instructions prior to the malloc exception triggered at the time of discovery? The lead suspect in the case seems to be the vector sink. I know using vector sink blocks is shunned and I feel very naughty for doing so but it is making it possible for me to do significant research without having to deep dive into C++. I'll try and think of some clever test cases to put the vector sink through its paces to trigger the error in a different context., On Mon, Apr 30, 2018 at 1:28 PM, Müller, Marcus (CEL) <[email protected]> wrote: > Ah, by the way, the function names where that error occurs are mangled > C++ names; I'll try to show what is what (using `c++filt` to demangle > the names) > > > /lib64/libc.so.6(+0x7dd4d)[0x7fa14f448d4d] > > /lib64/libc.so.6(__libc_malloc+0x4c)[0x7fa14f44afbc] > OK, that's malloc; are we certain that this has anything to do with > `free`? > > /lib64/libstdc++.so.6(_Znwm+0x1d)[0x7fa145c0e0cd] > "operator new(unsigned long)" > so, we're reserving space.
