--- Comment #4 from Andreas Otto  ---
change my C++ wrapper from "embedded data" (large amount of data) to just an
embedded pointer (only 8byte pointer in the C++ class)

→ the error is still there…

[Bug c++/85471] closing a "thread" in "C++" using "pthread_exit(NULL)" creates a "SIGABRT"

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85471

--- Comment #2 from Andreas Otto <aotto1...@t-online.de> ---
this is not as easy because this is a non trivial SW… what I mean… to just use
my test-case you have to setup a whole environment… the basic of a SW is a
client/server application using a non trivial protocol…

it is possible you send me a hint to create a better error output for you… for
me it would be perfect if the GCC part of the error could be MORE specific
about the real reason of the SIGABRT

thanks for your work.

Problem
===

In one of my TEST-Cases… written for my own server-software… I close a
(worker)-thread using the following code…

> pthread_exit(NULL);

in "C" this works fine… in "c++" I get the error from below… covered with
"valgrind"…

question: why I get this error in "system" code
