d7508d8c09 src: pefile.cpp: replace "membuffer + x - y" with "membuffer + (x - y)" 
This is needed because "membuffer + x" is now bounds-checked, and
the temporary addition would trigger an exception.

077793fa5e Update pefile.cpp 
I found a bug by participating to the Binary Golf Grand Prix 3 (https://tmpout.sh/bggp/3/) : upx text.exe segfaults when NumberOfSections in the IMAGE_FILE_HEADER is NULL, so 
if (memcmp(isection[0].name,"UPX",3) == 0) triggers a NULL pointer dereference causing a crash.
To fix it, just have to check if isection is NULL (which means NumberOfSections = 0) or not.
