Joost, perhaps you can narrow it down further by using a debug counter.
You'd have to add a debug counter to dbgcnt.def, say "frontend1"
Instead of "if (0 ...)", you would add'd do "if (dbg_cnt (frontend1) ...)".
Then compile with -fdbg-cnt=frontend1:N where N is a number, run, and see if
the bug occurs. The trick is to find the greatest value for N where the bug
occurs. This can be done with a binary search, as explained in dbgcnt.def.
