Judging by the many eh failures, I assume that you are using an old
version of gas ?

Required gas version? (was: Re: Results for haifa-disabled egcs-971105 g++ testsuite on i586-pc-linux-gnulibc1)

Exactly what version of gas should be sufficient and where I could find it?? I
recently installed egcs-971023 with pgcc-patches to my Debian/Ix86-box and
noticed that my own very simple EH-test dumps core. Fortunately I remembered
those warnings that old gas would cause EH not to work and I downloaded
gas-970915.tar.gz archive from ftp://ftp.cygnus.com/pub/egcs/infrastructure
assuming that it would be new enough version. After replacing my old Debian
1.3.1-distributed gas with that one, that EH-test still dumps core, so I guess
that gas wasn't new enough...

Thanks in advance!

I believe you should rebuild gcc after upgrading gas.

The one from binutils-2.8.0.1.15 works.  as -v reports

GNU assembler version 970731 (i586-pc-linux-gnulibc1), using BFD version
linux-2.8.1.0.15

Sorry, if you're going to use the pgcc patches, we have no way of
verifying that it isn't those patches that are breaking exception
handling.

I believe that it is.  However, there's still at least one EH failure
on Linux even with the new gas, so your test may still represent a bug.
Or the problem could be the pgcc patches.  Please post your test case.
If it works for others, then the problem may be the pgcc patches.
Another possibility is that your test case breaks for everyone.

If the failure is eh23.C, I have seen it in many other none-linux
reports.

And it will be fixed in the next snapshot.

I know, sorry if gave a wrong impression. I didn't want to bother
anyone with this potentially pgcc-specific EH-problem, so that's why I
tried just to ask about the version of gas, which hopefully was enough
egcs-specific subject, so that I could find out myself whether upgrading
would help or not.

I also tried my test with egcs-971023 (and gas-970915) without pgcc patches
and it also failed. Here's the code, in case someone is interested to
give it a try:

--- clip -----------------------------------------------------------------

#include <iostream.h>


class	Base {
    int	a;

public:
    void setValue(int value)	{a=value;}
};


class	Derived : private Base {
    char* ptr;

public:
    void setPV(char* p, int v)	{ptr=p; setValue(v);}
};


void a_function(void);
int foobar = 3;


int main()
{
    try {
        a_function();
    }
    catch (Derived a) {
        cout << 1 << endl;
    }
    catch (Base a) {
        cout << 2 << endl;
    }
    catch (...) {
        cout << 3 << endl;
    }

    return 0;
}


void a_function(void)
{
    Base        hmm;
    Derived     hmm2;
    int         hmm3;

    if (foobar == 1) {
        throw hmm;
    }
    else if (foobar == 2) {
        throw hmm2;
    }
    else {
        throw hmm3;
    }
}

--- clip -----------------------------------------------------------------

It's that "throw hmm3;" above that causes a coredump.

Thanks for your help!

I have no problem with egcs 971105 on linux/x86/libc 5 and linux/x86
glibc 2.1.

Yup, this is intentional.
