1090591 - test_dmd.js is broken on jemalloc3 builds

Status: RESOLVED FIXED

(Core :: DMD, defect)

Description

[Guilherme Gonçalves [:ggp]]

During the test, SmokeDMD.cpp does a 144-byte allocation, which is a size class in mozjemalloc, but gets rounded up to 160 bytes in jemalloc3, thus changing the output of DMD.

Bumping the allocation size to 160 and updating the expected output files fixes this. I'll do a Try
run with both jemalloc3 and mozjemalloc when Try is open again, but it works locally.

The test now passes on both mozjemalloc (https://tbpl.mozilla.org/?tree=Try&rev=57bc1e3f0eea) and jemalloc3 (https://tbpl.mozilla.org/?tree=Try&rev=7920942cbfb0) builds.
