Intermixing source code with disassembly

[Teng Chee Wan Philip]

Hi,

Thanks for the insight.  I used Msys for the objdump.  Well, in terms of
size, app application is definitely much bigger than the ticker example.
App is made up of several files compiled and linked together.

I tried the program you sent and modified it slightly to show the size
of file it managed to read.  I tried it on the ticker example as well as
my application.  In both cases, the read() failed and size read is much
smaller than the actual file size.

$ testobjdump.exe ticker.exe 
Read failed. fstat size 2303340 read size 7203 

$ testobjdump.exe app.exe 
Read failed. fstat size 1951944 read size 4851  

Regards,
Philip

 Is the size of app.c also very large?  objdump tries to malloc() an
area for the whole file at once; perhaps your Cygwin has some limitation
on heap size.

 I suggest to compile and execute the excerpt from objdump in
attachment. (objdump itself does no error reporting at all when it
cannot open/read the file...).  I hope you have a compiler?


 Good luck!
