Segmentation fault with make-4.3+ on MacOS with 'wildcard'

This is likely a bug with this old version of macos/xcode. (sending in this email to report this issue) This test works fine with: - default MacOS /usr/bin/make - brew make-4.4.1 - gnumake-4.2.1 compiled with xcode clang (version below) - gnumake-4.4.1 compiled with brew gcc (tried version 11) -

What a great looking bug report. Tiny reproducer, clear range of things tried, clear crash with an effort to debug it. But there's a problem. The stack trace includes: frame #7: 0x000196b1 make`variable_expand_string(line="", string="$(wildcard $(PETSCCONFIGDIR)/gmakegentest.py)"

Sorry - was a bit lazy - posted the stack trace from an earlier iteration where the test makefile has some more stuff [assumed it wouldn't make a difference wrt stack trace.] Satish balay@ypro ~ % cat makefile CONFIGDIR = ${PWD}/testdir/config ifeq ($(wildcard ${PWD}/testdir/readme),)

Re: Segmentation fault with make-4.3+ on MacOS with 'wildcard'

Is it possible that suspiciously half null pointer came from: https://git.savannah.gnu.org/cgit/make.git/tree/src/read.c#n3480 nlist = (const char **)gl.gl_pathv; ... and it's sliced off half the gl_pathv pointer through calling an implementation of glob that wasn't compatible with
