            Bug ID: 95367
           Summary: gcc crashed
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ferruh.yigit at intel dot com
  Target Milestone: ---

Created attachment 48619
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48619&action=edit
the gcc output with "-v -save-temps"

Please find below gcc log [1] and the source file it builds [2].

gcc version [3] is compiled from source, the commit of the source it has been
built is [4]. And full command line to build is [5].

Also compiled with additional "-v -save-temps" parameters, the gcc output
(gcc_verbose_command_output.txt) and the .i file (hinic_pmd_nicio.i) are also
attached.

Thanks,
Ferruh
