Subject: zsh malloc bug
Date: Tue, 1 Jun 2004 11:01:50 -0700 [thread overview]
Message-ID: <pdy988306110444bce26ff478d9@[209.128.98.50]> (raw)
Hi.
Z% echo $ZSH_VERSION
4.1.1
Z% uname -a
Darwin ip2 7.4.0 Darwin Kernel Version 7.4.0: Wed May 12 16:58:24 PDT 2004; root:xnu/xnu-517.7.7.obj~7/RELEASE_PPC Power Macintosh powerpc
I ran the script below and 1 second later hit ^C, eliciting this output:
Z% ./bug
^Cint
*** malloc[21559]: Deallocation of a pointer not malloced: 0x10f3c0; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug
Z%
Here's the script
==============
#!/bin/zsh
TRAPEXIT() {
echo exit
}
TRAPINT() {
echo int
exit
}
sleep 5
# Now type control-c
# or wait til here for a bus error
while true
do
sleep 1
done
==============
I have a slightly more complicated script that elicits two malloc debug printouts. I'll send it to whoever fixes this.
See also: my email with the subject "zsh needs try-finally".
