--- Comment #4 from Santhiar <santhiar.anir...@gmail.com> --- I have posted the backtrace again. Please also refer to the backtrace provided by AddressSanitizer that I have posted at the bottom of the original report - AddressSanitizer reports the first problematic memory access, along with stacks the allocation and free sites of that memory. Application: Ark (ark), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
