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.

2c2e108301 PE: fix comparison against a constant value 
... due to size always being assigned to right before this comparison,
and instead check against the RVA and size of the export directory
from the header. (note: this is still stricter than the Windows loader
which ignores all of these except the directory RVA, but if the name RVA
is invalid the PE was probably tampered with).
Change 'offset' to 'RVA' in exception message; this field is always an RVA
