Could anyone please give me a quick overview/point me to documentation of a way to inspect the stack (and heap?) of a C program? I thought this should be done with GDB, but if there are other more straighforward alternatives, then that should be fine as well.
Thanks.
View stack:
gdb> backtrace
View current stack frame:
gdb> info frame
View arguments of current stack frame:
gdb> info args
View local variable of current stack frame:
gdb> info locals
Navigate to parent stack frame:
gdb> frame 1
core_analyzer has gdb plugin and stand alone tool.
Latest version is only gdb plugin.
gdb plugin command shows memory statistic.
(gdb)
heap [/verbose or /v] [/leak or /l]
heap [/block or /b] [/cluster or /c] <addr_exp>
heap [/usage or /u] <var_exp>
heap [/topblock or /tb] [/topuser or /tu] <num>
stand alone tool has horizontal search and vertical search and it might be near what you expect.
[0] Print General Core Information
[1] Find References to an Object (horizontal search)
[2] What Is This Address and Underlying Object Type (vertical search)
[3] Objects Shared Between Threads
[4] Memory Pattern Analysis
[5] Query Heap Memory Block
[6] Page Walk (check the integrity of surrounding memory blocks)
[7] Heap Walk (check the whole heap for corruption and memory usage)
[8] Biggest heap memory blocks
[9] Biggest Heap Memory Owners (variables)
[10] Heap Memory Leak Candidates
[11] Quit
In my case, I could not get exprected result from core_analyzer.
