--- Comment #14 from Martin Liška <marxin at gcc dot gnu.org> ---
The original problem:

test.cc:3749:5: runtime error: member call on misaligned address 0x000041b58ab3
for type 'struct awaiter', which requires 8 byte alignment
0x000041b58ab3: note: pointer points here
<memory cannot be printed>

@Iain: How do you allocate the awaiter object?

@Rafael: Can you please append output with:
export UBSAN_OPTIONS="print_stacktrace=1"
