1579527 - elfhack segmentation fault with overlapping segments

Status: NEW

(Firefox Build System :: General, defect)

Description

[Nathan Froyd [:froydnj]]

With all the necessary fixes for bug 1577220 applied, a local PGO-instrumented build hits:

../../../dist/fennec/lib/armeabi-v7a/liblgpllibs.so: No gain. Skipping
../../../dist/fennec/lib/armeabi-v7a/libmozavutil.so: No gain. Skipping
../../../dist/fennec/lib/armeabi-v7a/libmozavcodec.so: No gain. Skipping
../../../dist/fennec/lib/armeabi-v7a/libxul.so: terminate called after throwing an instance of 'std::runtime_error'
  what():  Segments overlap
...
mozpack.errors.ErrorMessage: Error: Error executing /opt/build/froydnj/build-android/build/unix/elfhack/elfhack ../../../dist/fennec/lib/armeabi-v7a/libxul.so

This is a local build with LLD, so it's possible that this is an LLD bug?

elfhack doesn't really like the fancy stuff that lld tries to do (too fancy for its own good).
