Jim.

I now have a test case that reproduces this kind of crash every
time.


I was debugging Tcl 8.2.1 (tclsh) with my code that generates a
SIGPIPE error in tclsh when it crashed. At the time it crashed the process
had just been hit by a SIGPIPE and I hit the OK button. I am working
with the insight snapshot from 19991011 on RedHat Linux 5.2 (Intel).
I also tried this with gdb 4.17.0.4 and it did not crash.

I ran Tcl with the Run button and set a breakpoint in the file
tcl8.2.1/generic/tclPosixStr.c line 856. My version of Tcl 8.2.1
was built with --enable-gcc --enable-threads --enable-symbols
and --enable-shared. I then ran the following Tcl code in the terminal.


set port 6789

proc incomingConnection { stream addr port } {
    puts "incomingConnection from $addr $port"
    close $stream
}

set server [socket -server incomingConnection $port]

proc canWrite { } {
  global socket
  if {[eof $socket]} {
    puts "EOF ON SOCKET"
  }

  puts "Writing to socket"
  puts $socket "CLOSE"
}

set socket [socket localhost $port]
fconfigure $socket -buffering line -blocking 0
fileevent $socket writable canWrite

vwait forever



When the process was hit with a SIGPIPE, insight crashed
with the following stack trace.
