Valgrind - "client switching stacks"

2012-01-07T14:47:00.000-08:00

If you ever start to receiving following warning from Valgrind:

Warning: client switching stacks?

Followed by many error messages like "Invalid read/write" containing a note: "Address is on thread 1's stack" then the cause is very simple. You are just allocating too large variables on stack - in my case I had too large array, as local variable, in one of functions. If you can't or don't want to use heap it is possible to tune valgrind with "--max-stackframe" parameter i.e.

valgrind --max-stackframe=10485760 ./a.out

This will prevent false positive detection of stack switching up to 10MB.

One additional, much more obvious tip, use "-fno-inline" when building C++ binaries for use with valgrind, otherwise there won't be line numbers in stacktraces for any template functions.

Linia będzie dwutorowa, co oznacza, że pociągi będą mogły jeździć wahadłowo, bez oczekiwania na wolny tor
