Re: pkg/57145: gmake: *** INTERNAL: readdir: Operation not supported. Stop.

Hi,

I just observed this problem on NetBSD/amd64 10.1 with
gmake-4.4.1 while trying to build wip/wsjtx/, with:

gmake[5]: *** readdir .: Invalid argument.  Stop.
gmake[5]: *** Waiting for unfinished jobs....

The gmake is from NetBSD bulk build:

BUILD_DATE=2025-07-02 19:43:11 +0000
BUILD_HOST=NetBSD shadow.netbsd.org 10.0 NetBSD 10.0 (LIBKVER) #0: Tue Jan 19 00:00:00 UTC 2038 root@localhost:/sys/arch/amd64/compile/LIBKVER amd64

This is on a build done with MAKE_JOBS=40 on a 20-physical-cores
and 40 "virtual cores" with HT enabled system.

After the initial failure of this type, I decided to try to
capture the system call information with "ktrace -i", and as it
happened, the problem was reproduced with a ktrace.out file of a
mere 520MB.

The gmake system calls preceding this error were:

 14717  14717 gmake    CALL  lseek(6,0,0,1)
 14717  14717 gmake    RET   lseek 0
 14717  14717 gmake    CALL  __getdents30(6,0x79e73d4a0000,0x1000)
 14717  14717 gmake    GIO   fd 6 read 4080 bytes
...(omitted here)...
 14717  14717 gmake    RET   __getdents30 4080/0xff0
 14717  14717 gmake    CALL  lseek(6,0,0,1)
 14717  14717 gmake    RET   lseek 3132/0xc3c
 14717  14717 gmake    CALL  __getdents30(6,0x79e73d4a0000,0x1000)
 14717  14717 gmake    RET   __getdents30 -1 errno 22 Invalid argument

and it's all downhill from there.

Does anyone want access to the 520MB ktrace.out file for a closer
look, as there is (of course) intervening syscalls from other
processes in the process tree covered by the top-level make
invocation?
