firefox 38FBF249F41F7A64B3A6098BCC225F920 sym file has wrong debugid

[willkg]

I'm seeing a handful of ParseSymFileErrors in the Mozilla Symbolication Service starting August 11th for firefox 38FBF249F41F7A64B3A6098BCC225F920.

The file record on symbols.mozilla.org is here:

https://symbols.mozilla.org/uploads/files/file/48861769

The header looks like this:

MODULE Linux x86_64 65B29E6A53804B5D86B2D3497464C71C0 firefox
INFO CODE_ID 6A9EB26580535D4B86B2D3497464C71C4EEACF30
INFO GENERATOR mozilla/dump_syms 2.2.0

65B29E6A53804B5D86B2D3497464C71C0 does not match the debug id 38FBF249F41F7A64B3A6098BCC225F920.

Did dump_syms somehow put a different debug id in the file? Is this a problem elsewhere with the build?
