It seems that the default optimization option of MrC compiler is not compatible with -DENABLE_CHECKING. So those who want to use this should turn off the optimization flags as I wrote in the patch for mac/inc/s-mac.h.

Thanks for the comments. As far as I tested, GC_MAKE_GCPROS_NOOPS seems to work well with the default optimization option. But it crashes at the startup if used with "-opt off" option above for unknown reasons. YAMAMOTO Mitsuharu mituharu@math.s.chiba-u.ac.jp
