Hi all,
I need some help, to diagnose a problem.
I'm currently looking into an gmp issue.
A few gmp tests fail.
<for example>
make check-TESTS
make[4]: Entering directory `/usr/src/packages/BUILD/gmp-5.0.2/tests/cxx'
terminate called after throwing an instance of 'std::invalid_argument'
terminate called recursively
/bin/sh: line 5: 333 Aborted ${dir}$tst
FAIL: t-assign
</for example>
What I found it that they fail due to a try catch issue.
gmp-5.0.2/tests/cxx/t-assign.cc
// operator=(const char *) with invalid
{
try {
const char *a = "abc";
mpz_class b;
b = a;
ASSERT_ALWAYS (0); /* should not be reached */
} catch (invalid_argument) {
}
}
On b = a; the exception is generated. But it's not caught.
I don't know if it's related to g++.
Might this be a bug.
Can someone help, how to diagnose this problem?
Regards,
Joop.

What operating system are you using? Exactly how did you configure gcc?
What was the exact command line used to compile the file?

I'm using openSuSE ARM.
This is the gcc configuration.

The command line to compile and configure gmp ( http://gmplib.org/ ) are:
CFLAGS='-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables
-fasynchronous-unwind-tables -fexceptions'
./configure --prefix=/usr --libdir=/usr/lib --infodir=/usr/share/info
--build=armv7l-suse-linux --enable-cxx --enable-fat --enable-mpbsd
using ABI="standard"
CC="gcc -std=gnu99"
CFLAGS="-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector
-funwind-tables -fasynchronous-unwind-tables -fexceptions"
CPPFLAGS=""
CXX="g++"
CXXFLAGS="-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector
-funwind-tables -fasynchronous-unwind-tables -fexceptions"
MPN_PATH=" arm generic"
make 'CFLAGS=-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector
-funwind-tables -fasynchronous-unwind-tables -fexceptions' -j2
make 'CFLAGS=-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector
-funwind-tables -fasynchronous-unwind-tables -fexceptions' check
I also tried without : -funwind-tables -fasynchronous-unwind-tables
This didn't help.
I wonder if the unwind tables are really needed?

Thanks for the info. I don't see the compilation line--how g++ itself
was invoked--but I doubt it matters. I don't see anything wrong--this
does sound like a bug somewhere bug I don't know where.

Thank you for your time.
Dirk Müller found the possible cause.

When it's build we can test it.

I don't see how that could be the problem, but I'd be happy to be wrong.
