[OLSR-users] olsr on arm9 system on chip from intersil isl3893

[aaron]

ulf,

basically 16megs should be fine ;-)

did you use standard libc? or uclibc?

in standard libc there is as far as i remember an option for malloc debugging
Some environment variable needs to be set. I can't find it 
right now but it _is_ documented in libc (google or info pages)

maybe that helps...

because olsr_malloc(..) basically _is_ the standard malloc.
of course the bug could be somewhere else.
