Re: [uclibc-ng-devel] [RFC PATCH] libpthread/nptl: Use arch-dependent unwind-forcedunwind.c if available

Using unwind-forcedunwind.c from nptl/sysdeps/pthread doesn't work well on ARM, see nptl/sysdeps/unix/sysv/linux/arm/unwind-forcedunwind.c for an explanation. The following code example shows what's wrong without the ARM-specific version. -------------------------------------------------------------------- struct Foo { ~Foo(); }; Foo::~Foo() {} void f() { Foo a; throw 0; } int main() { try { f(); } catch (int) { std::cerr << "caught" << std::endl; } return 0; } -------------------------------------------------------------------- Compile without any optimizations (it's important that Foo's destructor is not inlined) and link with -lpthread. The thrown exception is not caught as expected and the program aborts.
