Re: GCC 4.2.2 arm-linux-gnueabi: c++ exceptions handling?

[Sergei Poselenov]

Hello all,

I've found the cause of my problem - it's binutils 2.17.50.
Using ld 2.18, or even 2.17.90 creates workable libstdc++.so.

Regards,
Sergei

Hello all,

I've built the above cross-compiler and ran the GCC testsuite.
Noted a lot of c++ tests failed with the same output:

terminate called after throwing an instance of 'int'
terminate called recursively

Thread model: posix
gcc version 4.2.2

However, testing results in http://gcc.gnu.org/ml/gcc-testresults/2007-09/msg00570.html

states that this should work.

I even downloaded and built the exact pre-release version
used in the above tests and tried it - all the same.

I wonder could it be the kernel or Glibc/binutils issue?
I'm running 2.6.21.5, Glibc is 2.6 (Fedora Core 7 release),
binutils is 2.17.50.0.12.

Could someone having the 4.2 release series compiler configured for
ARM EABI target try this simple test:
----
extern "C" void abort(void);

#define CI(stmt) try { stmt; abort(); } catch (int) { }

struct has_destructor
{
    ~has_destructor() { }
};

struct no_destructor
{
};

int PI(int& i) { return i++; }

int main(int argc, char *argv[])
{
    (argc+1 ? has_destructor() : throw 0);
    CI((argc+1 ? throw 0 : has_destructor()));
}
----
Build as arm-linux-gnueabi-g++ -o cond1 cond1.C


Thanks for any feedback,
Sergei
