Crash in src/engine/gnump/gmp_mem.cpp

[stikonas]

Hi, I was trying to investigate a crash in LibKTorrent (https://cgit.kde.org/libktorrent.git/) and somehow it points to Botan. Although, the crash looks very strange, so maybe it is not Botan's fault... Any ideas?

Just before the crash I get the message terminate called after throwing an instance of 'Botan::Invalid_State' what(): Pointer released to the wrong allocator

Backtrace:

I think that would refer to the C++ version of Botan -> https://github.com/randombit/botan
