            Bug ID: 96492
           Summary: <built-in>: internal compiler error: Segmentation
                    fault
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: townsend at astro dot wisc.edu
  Target Milestone: ---

I'm attempting to build 10.2 from within a Docker container based on Centos
5.11, which ships with glibc 2.5 and gcc 4.1.2. (The reason I'm doing this is
I'm building a gcc-based SDK that should be able to run on crusty old systems).

I'm configuring with the following options:

../gcc/configure --build=x86_64-pc-linux-gnu
--prefix=/home/user/sdk2-tmp/mesasdk --with-mpc=/home/user/sdk2-tmp/mesasdk
--with-mpfr=/home/user/sdk2-tmp/mesasdk --with-gmp=/home/user/sdk2-tmp/mesasdk
--disable-multilib --disable-nls --disable-libsanitizer
--enable-languages=c,c++,fortran

During the build (make -j), I get ICEs:

Did GCC 10.1 work or any older version you tried to build this way in the past?

It's worked in 9.2, 9.3, and earlier releases; but not in 10.1.

If I try the build outside the Docker container, it works fine. So, there's
something about the Centos 5.11 toolchain/libraries that make it break.

Can you run
gdb --args ./cc1 -quiet -fself-test=../../gcc/gcc/testsuite/selftests /dev/null
-o /dev/null
and do
run
bt
?

--- Comment #5 from Rich Townsend <townsend at astro dot wisc.edu> ---
So, given that gcc 4.1.2 is really ancient, I've tried building 10.2 using gcc
9.3.0 instead (but still inside the Docker container). This builds fine, and in
fact I'm happy to go with this workaround.

However, might be worth noting somewhere that gcc 10.X cannot be built with gcc
4.1.2.

cheers,

Rich

Let's close it as invalid then.
