Bug ID: 41038
Summary: Crash with debug entries not fitting into 2^16 bytes
(dwarf < 5)
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: DebugInfo
Assignee: unassignedb...@nondot.org

exceeds size limit with dwarf < 5
Currently LLVM crashes when we have too many debug values and exceed the 2^16
byte size in DwarfDebug::emitDebugLocEntryLocation.
Attached is a reduced example (still has around 16k llvm.dbg.value calls),
which crashes with `clang -Os`.
I am happy to look into the issue, but I would appreciate your thoughts on what
to do if we have too many debug entries.
