Bug ID: 91394
Summary: C++ ABI incompatibility (stdexcept)
Product: gcc
Version: 7.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tomas_paukrt at conel dot cz
Target Milestone: ---
Some C++ programs cross-compiled with GCC 7.4.0 using -std=gnu++11 do not work
on a system which have glibc 2.25 cross-compiled with GCC 4.9.4 even if the
symbol _GLIBCXX_USE_CXX11_ABI was set to zero during cross-compilation.
There are several places in the file "stdexcept" like this:
> class out_of_range : public logic_error
> {
> public:
> explicit out_of_range(const string& __arg) _GLIBCXX_TXN_SAFE;
> #if __cplusplus >= 201103L
> explicit out_of_range(const char*) _GLIBCXX_TXN_SAFE;
> #endif
> virtual ~out_of_range() _GLIBCXX_USE_NOEXCEPT;
> };
A program that calls constructor out_of_range(const char*) will be using symbol
_ZNSt12out_of_rangeC1EPKc@GLIBCXX_3.4.21 which is not present on the old
system, so I suggest to change the conditional compilation on such places to
this:
> #if _GLIBCXX_USE_CXX11_ABI && __cplusplus >= 201103L
> explicit out_of_range(const char*) _GLIBCXX_TXN_SAFE;
> #endif
