xinyiZzz opened a new pull request, #22549:
URL: https://github.com/apache/doris/pull/22549
## Proposed changes
Jemalloc heap profile follows libgcc's way of backtracing by default.
rewrites dl_iterate_phdr will cause Jemalloc to fail to run after enable
profile.
TODO, two solutions:
1. Jemalloc specifies GNU libunwind as the prof backtracing way, but my test
failed,
`--enable-prof-libunwind` not work:
https://github.com/jemalloc/jemalloc/issues/2504
2. ClickHouse/libunwind solves Jemalloc profile backtracing, but the branch
of ClickHouse/libunwind
has been out of touch with GNU libunwind and LLVM libunwind, which will
leave the fate to others.
