testcase
Build the attached file. Note that I had to build it on Linux because clang on
Windows didn't produce a native executable with symbols that LLDB could read.
clang -g expr_test.cpp -o expr_test.elf
Run Windows LLDB on expr_test.elf, and run these commands:
p main
p foo
p _Z3fooi
With Windows LLDB I see:
(lldb) p main
(int (*)()) $0 = 0x00000000004004f0
(lldb) p foo
error: use of undeclared identifier 'foo'
error: 1 errors parsing expression
(lldb) p _Z3fooi
(int (*)(int)) $1 = 0x00000000004004d0
With Linux LLDB I see:
(lldb) p main
(int (*)()) $0 = 0x00000000004004f0
(lldb) p foo
(int (*)(int)) $1 = 0x00000000004004d0
(lldb) p _Z3fooi
(int (*)(int)) $2 = 0x00000000004004d0
Windows LLDB is not correctly demangling _Z3fooi and resolving that as foo.</pre>
