Richard, Thank you for the reply.
Yes, I understand that without a working testing case to repeat the error, it’s very hard to debug and fix the issue. However, providing a testing case for this bug is really challenging from our side due to multiple reasons… I will discuss with our building engineer to see what we can do. Or, I will try to debug and fix this issue myself… Qing > On Feb 9, 2021, at 2:18 AM, Richard Biener <rguent...@suse.de> wrote: > > On Mon, 8 Feb 2021, Qing Zhao wrote: > >> Hi, >> >> The bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96391 >> <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96391> >> <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96391 >> <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96391>> >> >> Bug 96391 - [10/11 Regression] internal compiler error: in >> linemap_compare_locations, at libcpp/line-map.c:1359 >> >> has been opened on 7/30/2020, and multiple users reported the same issue. >> >> For our important application, all the C++ modules failed with this bug when >> we use gcc10 or gcc11.
