linux

I get a crash like this:

#0  0x2c58def0 in raise () from /lib/libpthread.so.0
#1  0x2d9b8958 in abort () from /lib/libc.so.0
#2  0x2d9b7e34 in __malloc_consolidate () from /lib/libc.so.0
#3  0x2d9b6dc8 in malloc () from /lib/libc.so.0

I guess it is a heap corruption issue. uclibc does not have mcheck/mprobe. Valgrind does not seem to MIPS support and my app (which is multi-threaded) depends on hw specific drivers. Any suggestions to check the consistency of the heap and to detect corruption?

Is the heap actually a heap?

In .NET (and Java as far as I know), the area where objects are dynamically allocated is referred to as the managed heap. However, most documentation that describes how the managed heap works depicts it as a linear data structure, such as a linked list or stack. So, is the managed heap actually… >>> More
