Is it normal?!

[Alexandru Carstoiu]

Hello,

I would like to know if this is normal, though it seems to be a BUG. Given this makefile:

.SUFFIXES:
.PHONY : rule

r:=bau
i:=b
rule:
 @echo @$(if $(findstring $i,$r), T , F )@

the result of running "make" on it is:"@ T @"
However, if we change the value of $i by replacing the 5th line with:

i:=bu

the displayed result is NOT as expected, "@ F @", but "Segmentation fault (core dumped)".

This is valid for

PS: I've noticed the 3.79.1 works as expected, but decided to send the mail, still...
