<div class="moz-cite-prefix">Hi Prasath<br>
<br>
I still believe that the issue is not related to omniORB. In our
project we have been using <br>
omniORB-4.2.2 compiled with gcc 8.2.0 (using c++1z option which is
a synonym of the c++17) <br>
for the x86_64-pc-linux-gnu platform and it works flawlessly. It
should be either a compiler <br>
configuration issue or something inside your project.<br>
By the way did you try to run any of the omniORB examples compiled
with gcc 8.2.0?<br>
<br>
Cheers,<br>
Serguei<br>
<br>
PS: Here is our compiler configuration<br>
<br>
<blockquote>g++ -v<br>
Using built-in specs.<br>
COLLECT_GCC=g++<br>
Target: x86_64-pc-linux-gnu<br>
Configured with: configure --prefix=/gcc/8.2.0/x86_64-centos7
-with-system-zlib --disable-multilib --enable-languages=all
--with-gnu-ld --with-ld=/binutils/2.30/x86_64-centos7/bin/ld
--with-gnu-as --with-as=/binutils/2.30/x86_64-centos7/bin/as<br>
Thread model: posix<br>
gcc version 8.2.0 (GCC) <br>

<p class="MsoNormal">Hi Prasath<br>
<br>
You mentioned that in order to compile omniORB with c++17
option you have removed the 'throw'
<br>
specifications from some functions declarations. How did
you actually do that? Could it be
<br>
that you have made this modification in the following way:<br>
<br>
void f() throw (BadParam) => void f() throw () <br>
<br>
The crash which you get normally happens in one of the two
cases:<br>
<br>
1) A function declares 'throw(A)' but actually throws a
different exception 'B'.<br>
2) A function is declared as not throwing any exception
using 'throw()' declaration but actually throws an
exception.<br>
<br>
So I would suggest you to check that you have removed the
'throw(...)' specifications completely<br>
from all the functions concerned and don't have 'throw()'
terms left anywhere in these functions
<br>
declarations.<br>
<br>
Cheers,<br>
Serguei<br>

Just remove all the throw specifications. The only place
