Bug ID: 98432
Summary: [coroutine] leaked frame created using await_transform
Product: gcc
Version: 10.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: hering.t at seznam dot cz
Target Milestone: ---
I think I encounter a memory leak caused by implementation when using
await_transform to turn arbitrary type into awaitable. I track the number of
(internally) allocated coroutine frames and expect to see zero as the final
figure, one remains unfreed however.
cmd line: g++.exe gcc_coro_leak.cpp -std=c++20 -O3 -Wall -Wextra -fcoroutines
Platforms tested: avr, x86
Compilation output:
returned: 0
Execution output:
allocating frame, total count:
1
allocating frame, total count:
2
hello coro-world
deleting frame, remaining count:
1
Program returned: 0
