            Bug ID: 95329
           Summary: Metro 2033 Redux benchmark fails to start
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: 0xe2.0x9a.0x9b@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

Mesa: 11.3.0-devel (git-57763ee)
GPU: R9 390 (dynamic power management: disabled)
Linux kernel: 4.5.0
Kernel module: radeon

Steps to reproduce the issue:

1) cd ".steam/root/steamapps/common/Metro 2033 Redux"
2) mv metro metro.bin
3) ln -s benchmark.sh metro
4) Edit benchmark.sh and replace "./metro" with "./metro.bin"
5) Copy the file "user.cfg" (attached to this bug report) to directory
"110000106d2b5d5"
6) Start the Steam client from command-line
7) Start Metro 2033 Redux from the Steam client

Segmentation fault (core dumped) 
./metro.bin -benchmark benchmarks\\benchmark33 -bench_runs 1 -output_file
benchmark.log -close_on_finish

Notes:
- Running "gdb metro.bin core" does not provide useful information
- AMD drivers (fglrx) are working OK
- Step 5 is maybe optional, but I haven't verified this

Running "valgrind --tool=callgrind" for about an hour seems to indicate that
the issue may be linked to very slow shader compilation, but this is
inconclusive. AMD drivers (fglrx) start the benchmark much faster.

The game itself (excluding the benchmark) runs OK with Mesa.

The cause of the issue is in metro.bin, not in Mesa. Found via running
"valgrind benchmark.sh".

The following code fixes the issue:

$ cat posix_memalign.c
#include <errno.h>
#include <malloc.h>
#include <stdlib.h>
#include <strings.h>

int posix_memalign(void **memptr, size_t alignment, size_t size) {
        if(alignment < 32) {
                alignment = 32;  // Optional. Might boost memcpy().
        }
        size *= 2;       // Required
        void *p = memalign(alignment, size);
        if(!p && size) {
                return ENOMEM;
        }
        bzero(p, size);  // Optional
        *memptr = p;
        return 0;
}

$ gcc -m32 -shared -fPIC -O2 -g -Wall -Werror -std=c99 -o posix_memalign32.so
posix_memalign.c
$ gcc -m64 -shared -fPIC -O2 -g -Wall -Werror -std=c99 -o posix_memalign64.so
posix_memalign.c
$ export
LD_PRELOAD="$PWD/posix_memalign32.so:$PWD/posix_memalign64.so:$LD_PRELOAD"
$ .../Metro 2033 Redux/benchmark.sh

Still reproducible in July 2018.

Another workaround is possible with newer glibc:

GLIBC_TUNABLES=glibc.malloc.check=3 ./benchmark.sh
