RE: Hangs with NGPT 1.2.1

If you has an older version installed, did you do the two step installation,
i.e. configure; make; make install; make distclean; configure; make ? We got
tripped by this back a few internal releases when the spin lock alignment
had
changed but old headers still had the original, I kinda remember that the 
symptoms were very similar.

Subject: [pthreads-users] Hangs with NGPT 1.2.1


I have been trying, unsuccessfully, to run any of my tests with NGPT
1.2.1.  Even the tests that come with NGPT hang.  All of the threaded
prgrams I have tried exhibit the same behaviour.  Right after a call to
gettid, there is a modify_ldt followed by an endless stream of
nanosleeps.  Part of an strace below.  Has anyone else seen this?

old_mmap(0x40211000, 16232, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS, -1, 0) = 0x40211000
close(3)                                = 0
munmap(0x400a9000, 108084)              = 0
mmap2(NULL, 156, PROT_READ|PROT_WRITE|PROT_EXEC,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x400a9000
SYS_224(0x40032660, 0x40037f20, 0xe0, 0x400324cc) = 10723
modify_ldt(0x1, 0xbffff8bc, 0x10)       = 0
nanosleep({0, 2000001}, NULL)           = 0
nanosleep({0, 2000001}, NULL)           = 0
nanosleep({0, 2000001}, NULL)           = 0
nanosleep({0, 2000001}, NULL)           = 0
...
...

Thanks,
