This must be related to the debug info in bs.se. How did you compile that binary? It would be useful if you can upload both bs.se and perf.data so that we could debug.

from autofdo.

My cppflags is
-g -finline-functions -W -Wall -pipe -O3 -finline-limit=100000 --param large-function-growth=100000 --param inline-unit-growth=100000 -Wl,-rpath /home/
work/gcc5/lib64
perf.data.zip

perf.data.zip is my perf.data

from autofdo.

The flags looks fine. Please also include the binary file to reproduce the problem.

it's a little big....
you can cat bs.se.*.tar.gz > bs.se.tar.gz，and then unzip it，thanks

problem reproduced. This should be a bug in the current symbolizer. Internally, we have already switched to llvm symbolizer. I manually verified that with llvm-symbolizer, the problem is gone. I think the right solution would be porting llvm-symbolizer here. I will consult about how to prioritize this and set an ETA. At the same time, if this is emergent issue, feel free to send merge request to fix this in the current symbolizer.

Thank you！ This is an emergent issue, please send a merge request to fix this in the current symbolizer.

from autofdo.

Sorry if my previous reply is unclear. This problem is not blocking us as we already moved to llvm symbolizer. And there is fix planned for the open-source version: porting llvm-symbolizer into github. As a result, we won't have the bandwidth to fix the current symbolizer. But we welcome contribution to fix the current symbolizer.

With #65 merged, this problem should have been fixed. Please reopen if otherwise.
