Comment 2 by wfh@chromium.org, Jun 14 2018

Components: Blink>JavaScript>WebAssembly
the regression task failed so trying again

as a datapoint, I can repro on 53686, CF is reproing on 53736.

I can also repro on v8 6.7.288.46 but the assert happens at a different place:

Fatal error in ../../v8/src/wasm/module-compiler.cc, line 518
Check failed: !thrower.error().
