A bug report about VM Structs stack walker on Alpine #1317
Description
Describe the bug
Hi,
Using my reproducer code, I found the following problems, and I'm investigating...
- On Alpine 3.10, the stacks are not correct if use VM Structs stack walker, while the stacks of
dwarfandagctwalker are correct. - On Alpine 3.21, the stacks are not correct if use VM Structs stack walker, the stacks of
dwarfandagctwalker are not correct too (manyunknownframes between kernel frames and java frames), but still readable. If use VM Structs stack walker, I have to add--jstackdepth 512, otherwise the html file can not be displayed by Chrome browser, some stacks are too deep (default 2048), beyond the capability of Chrome.
