[uclibc-ng-devel] Re: 回复: 回复: 回复: 回复: TLS memory-leak with dlopen

Hi, Certainly. Please refer to the attached file for the extended patch applicable to all architectures using NPTL. It has been verified on both x86 and mips64 architectures. best regards Lumingxiang -----邮件原件----- 发件人: Waldemar Brodkorb <wbx(a)openadk.org> 发送时间: Tuesday, October 15, 2024 7:40 PM 收件人: lumingxiang (操作系统开发部/NingOS, RD) <lu.mingxiang(a)h3c.com> 抄送: Waldemar Brodkorb <wbx(a)openadk.org>rg>; devel(a)uclibc-ng.org; zhangchun (操作系统开发部/NingOS, RD) <zhang.chunA(a)h3c.com> 主题: Re: [uclibc-ng-devel] 回复: 回复: TLS memory-leak with dlopen Hi, okay, thanks for the hint. I could reproduce the issue. Unfortunately the patch is x86_64 specific. Would you be able to extend the patch for all architectures using NPTL? best regards Waldemar Lumingxiang wrote, > Hi, > Waldemar Brodkorb, > I apologize for forgetting to mention earlier that Valgrind was initially unable to detect the memory leak.
