            Bug ID: 97217
           Summary: C++ program compiled with GCC crashes
           Product: gcc
           Version: 10.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: carsten.schmidt-achim at gmx dot de
  Target Milestone: ---

Created attachment 49277
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49277&action=edit
Example assembly listing causing the crash.

During development of my vector/matrix library using template meta programming,
I discovered that my test program crashes on some occasions when being compiled
with GCC.

When inspecting the assembly code generated by GCC, the instruction crashing
the program
seems to be unrelated to the data flow of the program.

I will attach the generated assembly of one of my test cases, which crashes the
program.

Please let me know if you would like to investigate further and how I can be of
service!

Sorry for the inconvenience!

o  the exact version of GCC

o  the system type

o  the options given when GCC was configured/built

Please confer to file output.txt.

o  the complete command line that triggers the bug

The program needs to be invoked either

unittest_array.exe [direction]

OR

unittest_array.exe [inverse]

Both test cases crash the program; other test cases do not seem to be affected.

o  the compiler output (error messages, warnings, etc.)

Again, please confer to file output.txt.

o  the preprocessed file (*.i*) that triggers the bug

Please see the attached archive ii_files.zip.
