#231 Decompress produces a crashing program
Both of these files compress nicely with upx -i node.exe
http://nodejs.org/dist/v0.10.26/node.exe
http://nodejs.org/dist/v0.10.26/x64/node.exe
However when I run upx -d node.exe on the resulting exe it crashes when run, I'm not sure how typical this is. Also I've tried compiling the source with vs2010 express and with vs2013 express, in both cases the same problem occurs.
Which version of UPX did you use? I was unable to reproduce the crash using v3.91 under linux+wine.
I'm using UPX 3.91w and i'm running on windows 8.1 64bit UK locale

Unfortunately I'm still unable to reproduce the crash. Now I used UPX 3.91w to compress and uncompress your test file, but there is no crash under wine :-/
And I'm not sure how to interpret the APPCRASH stuff.
Maybe you could try adding some command line options like:
--compress-exports=0 and --strip-relocs=0 ...
The exe i sent you crashes in window 8.1 x64 and window 7 x64
this exe was produced with
upx -i node.exethenupx -d node.exeI've tried turning off options in compression and it does not work.
The compressed version is always working fine, the decompressed version
always crashes. I'm not sure how to work out what the appcrash means either.
