I'm experiencing frequent cashes of llvm-dsymutil when building Rust projects with debug info (cargo build).

The LLVM bug report for the crash itself concludes that it's fault of invalid debug information provided, with NULL DIE.

libxul.so in image.tar.bz2 in the Linux Firefox build here https://tools.taskcluster.net/groups/HvVI2bceT4qJ71SN6rZo0A/tasks/BSJE8VonQuKKq1SJMK2Q8A/runs/0/artifacts may have the same issue. The rust compilation unit at debuginfo offset 0x396207cc contains

< 9><0x000be2ff>                    DW_TAG_inlined_subroutine
                                     DW_AT_abstract_origin       <0x0064dfea>

but 0x0064dfea is beyond the end of the compilation unit.

visiting for wg-debugging triage

does anyone know if this is still a problem?
