Bug ID: 30517
Summary: realpath() implementation has a C++ ODR violation
Product: glibc
Version: 2.39
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: ayzhao at google dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
In stdlib/bits/stdlib.h, realpath is implemented as an inline function whose
definition changes depending on whether or not limits.h was included first
before stdlib.h [0]. In C++, this leads to an ODR violation if, for example,
one translation unit includes stdlib.h and another translation unit includes
limit.h and stdlib.h.
