According to https://stackoverflow.com/a/27304253/3782797 (answer to "Is it bad practice to create a thread in a shared library?"), this is an API issue. Since this also changes the behavior of the library in an incompatible way, this also breaks the ABI. So I'm increasing the bug severity. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
