Hi,
on latest snapshots after 2010-07-07, I am picking random segfault building or configuring several programs
e.g building the snapshots itself
config.status: creating reent/Makefile
../../../../cygwin-snapshot-20100730-1/newlib/libc/configure: line 15352: 6896 Segmentation fault $SHELL $CONFIG_STATUS $ac_config_status_args
configure: error: ../../../../cygwin-snapshot-20100730-1/newlib/libc/configure failed for libc
make[1]: *** [configure-target-newlib] Error 1
or
checking for inttypes.h... yes
checking for stdint.h... yes
checking for unistd.h... yes
Segmentation fault
the segfaults are very elusive, and I did not succeeded yet to
build a simple test case.
Anyone having similar problem ? I am using a XP SP2
2010-07-07 has no problem while 2010-07-18 to 2010-07-30
have it.
Marco

Does this mean that 2010-0707 does not have problems?

Actually, I'd be particularly interested in knowing if 2010-07-18 has
the problem.

It is very elusive and it does not happen all the time,
just most of the time; every snapshot segfault in a
different point of the building and some time also
the same snapshot behavior differently.
I guess is due to some type of race but no clue how to
pin point it.

It's sort of a race but it's really more of an incredibly stupid thinko
on my part owing to the fact that I "optimized" some of the signal
handling. I almost knocked myself with the head slap out when I finally
saw the simple problem.
This should be fixed in today's snapshot.

confirmed.
No problem building several packages using the 2010-08-01
snapshots.
