Hi, The syslog function in my program (which runs in kernal mode) is crashing. From the stack trace I found that, the malloc function is causing heap correption in between the syslog calls. Iam using redhat6.1 with glibc2.1.x.i386.rpm. To narrow down the problem, I have added some more syslog messages, that time the application is not crashing. So it is very clear that syslog function in turn uses malloc (actually syslog calls vsyslog and vsyslog calls malloc) and because of some reason it is corrupting the heap and it crashes. Iam not using any signals in my program. But Iam using callback functions. This is my stack trace, (gdb) bt #0 0x258d3ea8 in malloc () from /lib/libc.so.6 #1 0x258d35ce in malloc () from /lib/libc.so.6 #2 0x258ce15c in open_memstream () from /lib/libc.so.6 #3 0x25929360 in vsyslog () from /lib/libc.so.6 #4 0x259292bf in syslog () from /lib/libc.so.6 : : : Will MALLOC_CHECK_ environment variable will help me out in some way? Iam getting really bugged of with this bug. It will be a very big relief, if somebody could help me out on this.
