This is for Wine, a regression that happened in the last week or two:

/files/pfeifer/gcc/bin/gcc -c -O2 nbcmdqueue.i
nbcmdqueue.c: In function ‘NBCmdQueueCancel’:
nbcmdqueue.c:107:7: error: Incompatible types in PHI argument 1
struct _NCB *

UCHAR

D.9146_56 = PHI <D.9167_60(8), D.9168_61(9)>

nbcmdqueue.c:107:7: internal compiler error: verify_stmts failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.


Interestingly enough, if I use -O1 instead of -O2 the failure remains,
alas a few lines earlier.
