I am running Ubuntu 18.10 (dev) on ppc64le under wayland. I get this crash with the packaged browser, and reproduced it with a local build of trunk (changeset:   427367:4aa8eb6e5ca7)

The above is a bit confusing. 
Can you please confirm that the crash reproduces with Mozilla Nightly official build? (if it does a crash report should be also be available-> about:crashes)(https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US)

I'm also inclined to believe that the comment 0 report is either a instability in 18.10 or something related to the build in the canonical version or maybe even some wayland related issues.

But I'd also thread carefully and not dismiss this without proper investigation. Let's involve some people who have a better idea than myself on what might be going on here before advancing anywhere with this issue. Tom, Mike can you take a look at this?

These builds are for x86, so I can't reproduce using those. This is why I did my own build.

Can you explain what you find confusing?

I guess it was I that I am just that unfamiliar with PPC arhitecture :). Apologies for the extra leg information I've asked for.

If the line information is correct, the corresponding code is:
    old_ndirty = chunk->ndirty;

which is puzzling, as chunk is not a null pointer, and looks like a valid chunk address.

Can you paste the output of the following gdb commands:
- print $_siginfo
- info proc mappings

i did a re-build with debugging turned on, and I hit this assertion:

Assertion failure: aSize <= gMaxLargeClass, at /home/joel/src/mozilla-central/memory/build/mozjemalloc.cpp:2532

Program received signal SIGSEGV, Segmentation fault.

    at /home/joel/src/mozilla-central/memory/build/mozjemalloc.cpp:2533
2533	  MOZ_ASSERT((aSize & gPageSizeMask) == 0);


I've since applied this patch, as it's (mostly) true on ppc64 these days:

It's a patch that appears to be carried by Debian and Fedora, for a number of years.

What is your kernel page size?

    
    

    
  
(try the `getconf PAGE_SIZE` command)

    
    

    
  
$ getconf PAGESIZE
65536

All the current ppc64 distros are 64K.

    
    

    
  
ppc64le doesn't #define __powerpc64__?

    
    

    
  
It does: 

$ clang -dM -E - < /dev/null | grep powerpc
#define __powerpc64__ 1
#define __powerpc__ 1

    
    

    
  
So without MALLOC_STATIC_PAGESIZE, you should be under:

#elif defined(__powerpc64__)
static const size_t gPageSize = 64_KiB;

which should work.

    
    

    
  
That is, you should have the same values for gPageSize, gMaxSubPageClass, gNumSubPageClasses, gPageSize2Pow, gPageSizeMask, gChunkNumPages, gChunkHeaderNumPages and gMaxLargeClass with and without MALLOC_STATIC_PAGESIZE. Can you check that out?

I think it's the other way around? 

We don't enter that ifdef block when MALLOC_STATIC_PAGESIZE is not defined, so we end up with the non-cost gPageSize.

Without static pagesize:

(gdb) p gPageSizeMask 
$1 = 65535
(gdb) p gPageSize
$2 = 65536
(gdb) p gMaxSubPageClass 
$3 = 32768
(gdb) p gNumSubPageClasses 
$5 = 6 '\006'
(gdb) p gPageSize2Pow
$6 = 16 '\020'
(gdb) p gPageSizeMask
$7 = 65535
(gdb) p gChunkNumPages
$8 = 16
(gdb) p gChunkHeaderNumPages
$9 = 1
(gdb) p gMaxLargeClass
$10 = 983040

With static pagesize (64k):

(gdb) p gPageSizeMask 
$1 = 65535
(gdb) p gPageSize
$2 = 65536
(gdb) p gMaxSubPageClass 
$3 = 32768
(gdb) p gNumSubPageClasses
$8 = 6 '\006'
(gdb) p gPageSize2Pow
$9 = 16 '\020'
(gdb) p gPageSizeMask 
$4 = 65535
(gdb) p gChunkNumPages 
$5 = 16
(gdb) p gChunkHeaderNumPages 
$6 = 1
(gdb) p gMaxLargeClass 
$7 = 983040

So yes, the sizes come out the same.

    
    

    
  
So how come this works when you disable MALLOC_STATIC_PAGESIZE and doesn't when you don't?

    
    

    
  
Also, with aSize = 65536 and gMaxLargeClass 983040, how can you hit this assertion:

Assertion failure: aSize <= gMaxLargeClass, at /home/joel/src/mozilla-central/memory/build/mozjemalloc.cpp:2532

    
    

    
  
It doesn't work in either case. I was letting you know that I'd applied that patch; I think we can ignore that though.

Here's the full backtrace that I'm seeing now, with --enable-debug:

Assertion failure: aSize <= gMaxLargeClass, at /home/joel/src/mozilla-central/memory/build/mozjemalloc.cpp:2532

I have this issue too on 60.3 ESR on debian stretch ppc64le

I think it should fixed asap considering firefox is completly unusable

    
    

    
  
Bug 1507035 might fix this. Can you check if that's the case?

Thanks Mike! I did a build without --disable-jemalloc and it launches. I think we can close this one.
