Hi,Ok, I'll take a look.
it is really nice to see fwprop in ;). There seems to be some memory
consumption issue on huge CFGs however. There seems to be some weird
noise in the mmap/sbrk numbers I didn't yet chance to analyze, but 45%
on PR28071 looks quite off the noise.
THat thing consist of very huge CFG consisting of expanded MIN/MAX
functions (many diamonds)...
