[Q] Possible to compress EXE with UPX?

G'Day,

Can madSHI 2.7 be used with UPX and still get a sensible stack trace? ie Is it possible to use any EXE compressor and get a sensible stack trace?

TIA

I don't know about v2.x but certainly madExcept v3.x can be used in conjunction with UPX and all functionality works as it should, including stack traces.

madExcept 2.x can be used with Petite and AsPack, but not with UPX. The reason is that UPX changes the PE header information and does NOT change it back after uncompressing the exe in memory. I consider that a bug.

madExcept 3.x can be used with UPX, because there I've simply stored the header information during compile time, so in other words: madExcept 3.x is able to work around the UPX bug.
