Memory leaks on compilations

Finally, unbelievable! This is what I love about UNIX systems. You're never hopeless!
So, I've done all the steps, but the problem was actually an endless call of a make option!
I have a script which calls debuild and gives it the `-j' option, then debuild calls dpkg-buildpackage and gives it the same option again, then dpkg-buildpackage calls make and gives it the same option...
I was using -j2, and had already tried changing it, but I ended unsetting it, so it was being called without arguments. From `man make':
"make will not limit the number of jobs that can run simultaneously", very enough!.
Also, strange that when called as -j2, it was enough for it to go nuts. Without the option -j, memory usage is relatively low!
See: https://forums.gentoo.org/viewtopic-...6-start-0.html
When compiling icecat, memory usage reached 7GB!!! I still believe this is a bug in make.
EDIT: my intention was using both CPU cores to compile faster, so does it mean it is not possible?
Thank you so much!

Of course it is possible
But when you build thru scripts the -j option is very often badly handeled ,
i forgot where, but passing to scripts like make-kpkg i think, -jX will break the whole process of the compilation if passed by hand
but if you put it in /etc/make-kpkg.conf (i think (i dont have all the names in mide)) it will be just fine
i just love seeing the 4 procs at 90% working and gcc runing all over the place That's why I usually go or all manually , or all automatically by editing conf files ...
Voila
have a great one|

PAPS(1) General Commands Manual PAPS(1) NAME
paps - UTF-8 to PostScript converter using Pango SYNOPSIS
paps [options] files... DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves through the pango ft2 backend. OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. --landscape Landscape output. Default is portrait. --columns=cl Number of columns output. Default is 1. --font=desc Set the font description. Default is Monospace 12. --rtl Do rtl layout. --paper ps Choose paper size. Known paper sizes are legal, letter, a4. Default is A4. --bottom-margin=bm Set bottom margin in postscript points (1/72 inch). Default is 36. --top-margin=tm Set top margin. Default is 36. --left-margin=lm Set left margin. Default is 36. --right-margin=rm Set right margin. Default is 36. --help Show summary of options. --header Draw page header for each page. --markup Interpret the text as pango markup. --encoding=ENCODING Assume the documentation encoding is ENCODING. --lpi Set the lines per inch. This determines the line spacing. --cpi Set the characters per inch. This is an alternative method of specifying the font size. --stretch-chars Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops behaviour. AUTHOR
