Re: make: *** virtual memory exhausted. Stop.

[Paul D. Smith]

I ran your script and generated the directory structure.  I then ran
make -R using the latest CVS source built with debugging but no
optimization, with valgrind.  The results are:


$ valgrind /app/global/.builds/psmith/gmake/make/make -R

completed successfully
==20399== 
==20399== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
==20399== malloc/free: in use at exit: 3159739 bytes in 40393 blocks.
==20399== malloc/free: 191560 allocs, 151167 frees, 3280102073 bytes allocated.
==20399== For a detailed leak analysis,  rerun with: --leak-check=yes
==20399== For counts of detected errors, rerun with: -v


So, no memory leaks, buffer overruns, etc.  GNU make did have 3.1M of
dynamic memory allocated when it exited.  Given 10,000 targets (remember
every makefile is considered a target, so that we can do auto-re-exec)
that's 315 bytes per target if _ALL_ that RAM were used only for storing
targets, which it is not of course.
