Hey all,

I have written some code to analyze massive gzipped files (using std.iopipe), tested it on small subsets of the gzip files, and everything works using small 20 to 50 Mb files.

However when I try to run the code on 2.7 Gb file sizes the program always crashes with the following error:

"Program exited with code -11"

No other messages, did anyone ever encounter something like this before / got any ideas on how to figure out what is wrong ?

Not signal 11? On unix/linux I assume?

It's on linux yes...

No idea if it is a signal or an exitcode, the only indication is the text:
"Program exited with code -11"

Same thing. This is a segmentation fault.

Compile the program with the -g switch to dmd, then run it inside the gdb program


gdb --args ./your_program any_args_to_your_program

the hit the "r" command to run and when it crashes, it will tell you where. probably a null pointer.
