Hello,

I spend much of time in reproducing a testcase - I hope that this problem can 
be reproduced by others too.
While looking for a testcase for reproducing our other problem with "Bad 
address" errors - I tried to build cygwin snapshot 20111213.

I did a fresh cygwin intallation for this test.
I installed snapshot cygwin-inst-20111213.tar.bz2.
I run rebaseall and peflagsall and did a reboot.

$ uname -a
CYGWIN_NT-6.1-WOW64 PCFX061 1.7.10s(0.255/5/3) 20111213 04:12:34 i686 Cygwin

Here is my configuration
$ cygcheck -c >cygcheck.log
ftp://temp3-ro:tempro AT ftp DOT arburg DOT com/temp3/make_strace.log

Her you will find an strace of the problem:
$ strace -o make_strace.log make -j2
ftp://temp3-ro:tempro AT ftp DOT arburg DOT com/temp3/cygcheck.log


I've downloaded cygwin-src-20111213.tar.bz2.

running make -j2 in /cygwin-snapshot-20111213-1/i686-pc-cygwin/newlib/libc/argz
will produce the following error:

Running without -j flag all works fine.

I did the following steps: running configure and run make without -j flag for 
the first build:

$ tar xjf /cygdrive/c/Programme/cygwin/mirror/snapshots/cygwin-src-
20111213.tar.bz2
$ cd cygwin-snapshot-20111213-1
$ md myinstall
$ ./configure --prefix=/src/cygwin-snapshot-20111213-1/myinstall
$ make

Then I tried make using -j flag in a sub directory.
$ cd i686-pc-cygwin/newlib/libc/argz
$ rm *.o
$ make -j2

I hope other users can reproduce same problem.

regards

Heiko
