Re: posix_spawn issue?

[Ryo ONODERA <ryo%tetera.org@localhost>]

Hi,

I have uploaded simple test Makefiles:
https://www.netbsd.org/~ryoon/gmake-tests-20210502.tar.gz

It is as follows:

$ cat Makefile
all:
        ${MAKE} -C test-a

clean:
        ${MAKE} -C test-a clean


$ cat test-a/Makefile
all: a.txt

a.txt:
        touch a.txt

clean:
        rm -f a.txt


Results is here:

Without posix_spawn:
$ gmake
gmake -C test-a
gmake[1]: Entering directory '/home/ryoon/gmake-tests/test-a'
touch a.txt
gmake[1]: Leaving directory '/home/ryoon/gmake-tests/test-a'


With posix_spawn:
$ gmake
gmake -C test-a
gmake: *** [Makefile:2: all] Error 127


The tarball also includes a result of 'ktrace gmake' in posix_spawn case.

I wish this could be useful for debugging.

Thank you.
