Bug ID: 93475 Summary: With 100k+ mangled names, appears to incorrectly mangle about 15% causing demangle failure Product: gcc Version: 9.2.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: simonhf at gmail dot com Target Milestone: --- When looking at over 100k mangled C++ names, many of them fail to demangle using common command line tools. Initially I thought this was the fault of the demangler and opened a bug here [1]. However, after opening a similar bug here [2] for the LLVM demangler, a detailed response from LLVM developers appears to suggest that g++ itself is mangling incorrect, so I opened this bug!
