Bug ID: 222562
Summary: c++filt and libelftc do not demangle names correctly
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
Created attachment 186669
--> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=186669&action=edit
Small c++ program to demonstrate the problem
If you compile the attached tester.cc source (just "make tester.o") then use
nm(1) on the .o file, the nm output includes two mangled symbol names:
00000000 V _ZTS3Foo
00000000 r _ZTSZ4mainE3Bar
Running them through c++filt gives:
# c++filt _ZTS3Foo _ZTSZ4mainE3Bar
typeinfo name for Foo
_ZTSZ4mainE3Bar
(The program also produces wrong output when it runs, but that will be handled
in a separate PR, becuase our current libcxxrt uses different demangling code
than libelftc).
