Comment (by thomie):

 This bug might depend on the platform you are on or the version of `gcc`
 you are using.

 For me, on Ubuntu (gcc 4.8.4) with HEAD, running 'make TEST=cabal01'
 creates the files you mentioned, but they get deleted before the test
 finishes.

 On msys2 Window (gcc 4.6.3) with HEAD, the following files are left behind
 in `/tmp`:
 {{{
 -rwxr-xr-x 1 ghc None 126940 Oct 19 10:25 570528145.exe
 -rw-r--r-- 1 ghc None   4729 Oct 19 10:26 ccgHM4XN
 -rw-r--r-- 1 ghc None   4729 Oct 19 10:26 ccqNwUwz
 -rw-r--r-- 1 ghc None   5874 Oct 19 10:25 ccysdfeq
 }}}

 I don't see any panics occuring.

 Running the same test on Windows with `TEST_HC=ghc-7.8.3` only leaves
 behind that `.exe` file, not the `ccXXXXXX` files.
