Hi,

sys-devel/make-4.2.1-r1 failed to compile with this:

Online I found articles which explain, why it is not recommended to
use alloca() at all:
RETURN VALUE The alloca() function returns a pointer to the beginning of the allocated space. If the allocation causes stack overflow, program behaviour is undefined.
(https://stackoverflow.com/questions/1018853/why-is-the-use-of-alloca-not-considered-good-practice)

How can I recompile make -- it is still non-PIE and one of those
application which I cant convince to be friendly to gcc :)

How serious is this alloca-thingy at all?

Cheers
