Output of regex.c with -E switch

Running on RISC OS 4.02 the compiler segfaults on a line with a macro which
expands to a simple for loop. I initially thought this was due to lack of
memory so dialled the wimp slot up to 28MB, but still happened.

Instead I installed on a BeagleBoard (more memory, bigger wimp slot!) but even
with 200MB slot and 200MB free it blew up.
Also tried disabling the optimiser.

The full sources are in the RISC OS Open repository
gpl/RiscOS/Tools/Sources/GNU/libgnu
the preprocessed file in question is attached. Note the repository copy has a
few conflicting definitions in "system.h" so doesn't compile out of the tin
currently.

Any known workarounds?
