Bug ID: 24638
Summary: Taking the address of std::string::c_str causes
undefined reference
Product: libc++
Version: 3.6
Hardware: PC
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: dasca...@gmail.com
CC: llvm-bugs@lists.llvm.org, mclow.li...@gmail.com
Classification: Unclassified
c_str is defined as force-inline, which causes the compiler to not emit it in
any translation unit. It is not included in libc++.dylib either. Taking the
address causes an undefined symbol to be emitted regardless, but the compiler
does not include the implementation.
As far as I can tell the compiler should emit the symbol if it is explicitly
used, even if it is marked as force-inline.
