So we manage to read in symbols from the executable file, but we error out while trying to read in debug info from a separate debug info file. I assume that this means we skip some of the initialisation of the shared library. N= ot sure whether that's part of this issue. I'll try to cook up a smaller reproducer for this. --=20 You are receiving this mail because: You are on the CC list for the bug.=
