Symbolization stability is extremely poor.

[wallycheng]

Symbolization fails; using tcmalloc to generate heap profiles, copying them to a secure environment for analysis with symbolized binaries—yet function names still do not appear. Stability is extremely poor. Moreover, I had no idea how to install it in an offline environment until, after one hour of Googling, I discovered it can be used via go tool pprof. However, documentation and usage hints are severely lacking.

PPROF_BINARY_PATH=~/tmpfs go tool pprof --text xxx.heap

output：
[xxx process]
[xxx.so]

~/tmpfs is where to store symbolized binaries, path is good with collection environment. It works pretty well with perf --symfs ~/tmpfs.

If anyone know how to help I appreciate.

Please post a full reproducer, right now it's difficult to give any advice because the description is pretty vague.
