Details:

Hello,

With the following Makefile, make-4.2.91 segfaults on my Solaris 10:

% cat Makefile
include /dev/null
dummy: subdir/*.c
include /dev/null
%

This needs some preparation: many files in subdir, including at least one
subfolder:

% mkdir -p subdir/subsubdir
% touch `seq -f subdir/%5.0f 11001 12000` # seq does not exist on my solaris,
yet you understand the idea
% make -d
GNU Make 4.2.91

Reading makefiles...
Reading makefile 'Makefile'...
Reading makefile '/dev/null' (search path) (no ~ expansion)...
Segmentation fault
%

Of course the two include's are not necessary, but are useful to pinpoint the
bug.
This 'make' was built with '--disable-posix-spawn'.

I insist that when there is no subfolder in subdir, no segfault shows up.

I was unable to reproduce on linux and/or cygwin. I have no access on Solaris
11.

Regards,

Denis Excoffier.
