* Is there any mechanism in GDB to print memory allocation pattern in a core dump file @ 2012-05-23 12:33 santoshp 2012-05-23 15:13 ` Tom Tromey 0 siblings, 1 reply; 4+ messages in thread From: santoshp @ 2012-05-23 12:33 UTC (permalink / raw) To: gdb Hi All, I got a crash for which the size of the core file is little bigger i.e. ~9GB. Initial impression is that there might be some memory leaks in the process as the size is bugger than the usual size. Is there any mechanism in GDB/Linux I can find out the memory allocation pattern in the core file? e.g. There is a tool debug diag in Windows which can do this nicely from dump file. Any pointers will be appreciated.

Nothing built in, but there is gdb-heap, if you're on a system using glibc. https://fedorahosted.org/gdb-heap/ Tom ^ permalink raw reply [flat|nested] 4+ messages in thread

Probably not as-is. gdb-heap relies on glibc. You could probably port it to your allocator, though. Tom ^ permalink raw reply [flat|nested] 4+ messages in thread
