Subject: strange segmentation fault in malloc()

Hi, there!

My app wants to read and then wavelet-transform image one by one. Now I got
a strange segmentation fault in malloc().  The situation is only the first
image can be processed successfully, but the second one fails due to the
same call of "malloc(160*120*sizeof(float))" used in the processing of the
first image. The return value of "malloc" is NULL . So how can I check the
size of heap used by the system? Or how can I set the environment varible
"MALLOC_CHECK_"? Someone said it can be set in the rc.sysinit, but I can't
find this file. Any suggestion will be greatly appreciated. Many Thanks!
