Linux linuxmafia 2.2.12 #8 Sat Sep 11 21:10:52 CDT 1999 i686 unknown
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
glib-2.1.2
Using Unix98 PTY's
Apache built with shared=max running mod_frontpage, mod_perl, php4, mod_roaming.
>Description:
This may be due to the unix PTY's or some other setting on the box but I have no way of
trying to see what it could be.  A strace on htpasswd reveals this:

open("/dev/tty", O_RDWR|O_CREAT|O_TRUNC, 0666) = 3
ioctl(3, TTY_MAGIC, {B38400 opost isig icanon echo ...}) = 0
ioctl(3, TCSETSF, {B38400 opost -isig icanon -echo ...}) = 0
fstat(3, {st_mode=S_ISGID|0400, st_size=0, ...}) = 0
mmap(0, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x40014000
ioctl(3, TTY_MAGIC, {B38400 opost -isig icanon -echo ...}) = 0
write(3, "Re-type new password: ", 22Re-type new password: )  = 22
read(3, "test\n", 4096)                 = 5
write(3, "\n", 1
)                       = 1
ioctl(3, TCSETSF, {B38400 opost isig icanon echo ...}) = 0
close(3)                                = 0
munmap(0x40014000, 4096)                = 0
time(NULL)                              = 937525822
--- SIGSEGV (Segmentation fault) ---
+++ killed by SIGSEGV +++
I do not know how to trace when a child dies the server remains running when this happens
when calling the FP module which I know is not your worries but it may be related at least 
I think it may.
>How-To-Repeat:
Run UNIX98 ptys and possible it may be glibc related as well not sure.
>Fix:
None what so ever, I would like to know if it is a bug or not if you have time to 
reply so I can look at something else.  If you need access to the machine let me know as well
Thanks.
