Re: make test: SEGV in t1127.cxx:24

2008-10-12T02:06:05Z

The SEGV error in t1127.cxx happens if all of the following 4 conditions are met:

1.) The error happens only in release-build, not in debug-build.

2.) The error happens under 64-bit platform (x86_64)

3.) It happens only if CINT loads a DLL-version of the h-File
via #pragma include, as in t1127.cxx:

#if defined(interp) && defined(makecint)
#pragma include "test.dll"
#else
#include "t1127.h"
#endif

4.) If a variable number of arguments are passed to such a DLL
that was loaded via #pragma include (see above).

In test/testall.cxx is an indication that t1127.cxx does not
work on some platforms because of unsolved var_arg problems:

#if !defined(G__APPLE)
// This not work on macos because of var_arg
ret += ci(kLangCXX, "t1127.cxx", difffile);
ret += mkci(kLangCXX, "t1127.cxx", "t1127.h", difffile); //
#endif // !G__APPLE

IMO the segment violation happens because the adress space
of the program seems not correctly mapped in the dll.
I once had a similar case under Win32 some years ago.
IIRC one had to "force" the DLL to switch to the right adress space
by calling a very low level system function, ie. a privileged kernel function.

Hi,

you are building in the same directory that you want to install into -
that won't work! Just do

make clean;
./configure --debug --checkstack;
make # NO make install!
. setenv.sh
make debugtest TEST=t1127.cxx

And then run the failing test (if any) with gdb. That should tell us
more. The new core is still unstable and under heavy development, so I
would recommend staying with the old one for now.

Cheers, Axel.

Re: make test: SEGV in t1127.cxx:24

2008-10-08T11:39:34Z

Summary of my new test:
I did svn up and got revision 25741.
I then configured for debug
Compiled using --coreversion=new
Results:
- make install fails (see below, but cint still works)
- make debugtest fails in file test/explicitdtor.cxx and stops there
- t1127.cxx passes in debug build, non-debug-build not retested yet with the new svn revision

Regarding explicitdtor.cxx: the question is now which one is incorrect, cint or g++ :-)
I hadn't time to analyse the explicitdtor.cxx throughly
to decide which one (cint or g++) is correct.
Ie. this is a difference in the program out, cint vs. g++.

The test t1127.cxx does no more bring the segment violation crash
(but this must be re-tested also in the non-debug version).

And I think the new test script stops at the first failed test
so the other test don't get executed after an error in any of the tests
(but I'm not sure if that is really so).

Re: make test: SEGV in t1127.cxx:24

> BTW, one thing I don't understand is why .configure says "Using old CINT core":

CINT is currently undergoing is significant overall of its internal structures
(we are replacing internal C style arrays and structs with a C++ library named Reflex).
The new code is not yet ready for primetime but is already available with the
configure option --coreversion=new
