Help with non-reproducible .debug_loclists
Nazar Kazakov is encountering non-reproducible DWARF debug information in the .debug_loclists section when building glslang with GCC. The issue manifests as variations in start/end values or other values within loclists, even when the source code is identical. Nazar is seeking insights into potential bugs or debugging strategies for this DWARF generation problem.
