I forget exactly how I came across this, but the definition of poison_pages in ggc-page.c is wrapped in #ifdef ENABLE_GC_CHECKING. But a call to it is wrapped in GGC_POISON, which is never defined. The result is that we don't poison things properly when we read in a pch file. Fixed with: 2003-10-31 Richard Earnshaw <rearnsha@arm.com> * ggc-page.c (ggc_pch_read): Wrap call to poison_pages in ENABLE_GC_CHECKING not in GGC_POISON.
