JS: `stgToJS` allocates 4 MB byte array but comment suggests it should be 4 KB
Summary
In compiler/GHC/StgToJS/CodeGen.hs
stgToJS logger config stg_binds0 this_mod spt_entries foreign_stubs cccs output_fn = do
...
bh <- openBinMem (4 * 1024 * 1000) -- a bit less than 4kB
...
But the comment is incorrect, this is not 4 KB, but 4 MB.
The relevant code in openBinMem
is:
openBinMem :: Int -> IO WriteBinHandle
openBinMem size
...
arr <- mallocForeignPtrBytes size
The comment should be updated, or openBinMem (4 * 1000)
should be used.
