-fcheck-memory-usage

[Sascha Ziemann]

Hi,

I tried to compile my code with the -fcheck-memory-usage, but I get
endless errors about chkr_set_right:

main.c:69: undefined reference to `chkr_set_right'

Is this function in any lib, or do I have to write such a function?  I
can not find any information about chkr_set_right in the info file of
GCC.
