Problem when linking objects files from IBM VAC++ and GCC

["Bruno Beaumont" <bbeaumont at sesinsud dot com>]

Hello,

I need to link together G++'s object files and IBM Visual Age++ 's object 
files. I pass "-lstdc++ -lgcc_s" at the  IBM ld command line.
I use G++ v3.3.2 and AIX v5.2.
The link is OK but I get a "signal 6" at execution time when an exception 
is raised.

The problem does not appear if:
- I use AIX 4.3.3 / gcc 2.95.3 / IBM C++
or
- I link with libstdc++ and libgcc_a version 2.95.3 (compiled on AIX 4.3.3) 
on AIX 5.2.

Is the compilation option for gcc abi support could resolve my problem ?

Moreover I would like to know if GCC 2.95.3 is compatible with IBM AIX v5.2 
(with IBM as and ld).

I tried to compile it and I got the following error after "configure" and 
"make bootstrap":
