Details

Currently MacOSX crosscompile buildsymbols seems to be missing the generation of the XUL symbols.

Even after a 'successful' generation of symbols, the XUL symbol dSYM tarball and .sym file were missing in the <objdir>/dist/crashreporter-symbols.

After much trial and error, it seems as if the symbolstore.py seems to be 'eating' up the
terminating error.

Particularly: https://hg.mozilla.org/mozilla-central/file/tip/toolkit/crashreporter/tools/symbolstore.py#l580

proc = subprocess.Popen(
cmd,
universal_newlines=True,
stdout=subprocess.PIPE,
)

As the <objdir>/dist/host/bin/dump_sys was built using the $CROSSCOMPILE$/macos/clang/lib path, I tried the following manual run:

$ LD_LIBRARY_PATH=/data/crosscompile/macos/clang/lib /data/tmp/build/build/macosx/llvm-dsymutil --arch=x86_64 /data/tmp/obj-mac/toolkit/library/XUL

$ LD_LIBRARY_PATH=/data/crosscompile/macos/clang/lib /data/tmp/obj-mac/dist/host/bin/dump_syms -g /data/tmp/obj-mac/toolkit/library/XUL.dSYM /data/tmp/obj-mac/toolkit/library/XUL
terminating with uncaught exception of type std::out_of_range: vector
Aborted

At this point, I'm somewhat stumped as to what the issue is. Since dump_syms worked on the other files [certutil et. al], I'm guessing that something is funky with the
creating of objdir/toolkit/library/XUL.

Filing this bug for reference.

Here's an strace, fwiw:

Apparently, the issue seems to stem from the build/build/macosx/llvm-dsymutil binary. WG9s provided a new set of binaries which I uploaded to the builder and after running "mach buildsymbols", the XUL symbols were generated.

So I believe the llvm-dsymutil generated XUL symbols that dump_syms didn't like. That said, I still don't understand why dump_syms didn't like just only the XUL the in-tree llvm-dsymutil generated. The other files were fine. File size issue? I'm keeping this opened just in case there is an answer.
