--- Comment #15 from Vojtech Fried  ---
I am also getting this error. Our code is a big python extension. I run python3
and use LD_PRELOAD. In our code it throws an exception that would normally be
caught.

(In reply to Martin Liška from comment #16)
> Is it public, so that I can reproduce that?

No, it is not public and it is also a large project, so it is not useful for
reproducing the issue. I am sorry.

Created attachment 43866
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=43866&action=edit
simple repro

I have added a simple way to reproduce it.
Unpack and run run.sh.
You need python3 installed (including dev packages).
It creates a simple python3 module and runs a python script using it. If built
and run with sanitizers, it will reproduce the problem.

[Bug libstdc++/71025] New: std::call_once aborts instead of propagating an exception (AIX 6.1)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71025

Bug ID: 71025
   Summary: std::call_once aborts instead of propagating an
exception (AIX 6.1)
   Product: gcc
   Version: 5.3.0
Status: UNCONFIRMED
  Severity: normal
  Priority: P3
 Component: libstdc++
  Assignee: unassigned at gcc dot gnu.org
  Reporter: vfried at opentext dot com
  Target Milestone: ---

When an exception is thrown inside a function called from std::call_once, the
process is aborted. The exception should be propagated outside std::call_once.

#include 
#include 
#include 

int main()
{
static std::once_flag flag;

printf( "start\n" );
try
{
std::call_once(
flag,
[&]()
{
throw std::runtime_error("thrown from once");
} );
}
catch ( std::runtime_error const& exc )
{
printf( "%s\n", exc.what() );
}
printf( "end\n" );
return 0;
}

bea@stbldap02:~/samples$ g++ -std=c++14 -pthread std_call_once_exception.cxx
bea@stbldap02:~/samples$ ./a.out
start
terminate called after throwing an instance of 'std::runtime_error'
  what():  thrown from once
IOT/Abort trap (core dumped)

BTW: the system on which I tested it should be the same as in
