Bug ID: 69738
Summary: memory-leaks (apache benchmark) ab with some options
Product: Apache httpd-2
Version: 2.5-HEAD
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: support
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
When we use some options strdup(opt_arg) is affected and allocated memory will
not free. When we build the project with address sanitizers:
$ export CC="clang"
$ export CXX="clang++"
$ export CFLAGS="-pipe -g -O2 -fstack-protector-strong -Wformat
-Werror=format-security -fsanitize=address,leak"
$ svn co http://svn.apache.org/repos/asf/apr/apr/trunk srclib/apr
$ <some buildconf calls>
$ ./configure --with-included-apr --host=x86_64-linux-gnu
--build=x86_64-linux-gnu --enable-layout=Debian --enable-so
--with-program-name=apache2 --enable-suexec --with-suexec-caller=www-data
--with-suexec-bin=/usr/lib/apache2/suexec --with-suexec-docroot=/var/www
--with-suexec-userdir=public_html
--with-suexec-logfile=/var/log/apache2/suexec.log --with-suexec-uidmin=100
--enable-suexec=shared --enable-log-config=static
--with-pcre=/usr/bin/pcre2-config --enable-pie
--enable-mpms-shared=all --with-mpm=prefork --enable-mods-shared="all brotli
cgi ident authnz_fcgi imagemap cern_meta proxy_fdpass proxy_http2 bucketeer
case_filter case_filter_in" --enable-mods-static="unixd logio watchdog version"
$ make
we got the leaks for running ./ab:

I suggest just replace any *strdup(opt_arg)* on just *opt_arg* such as many
cases (for instance option -x, -y and etc) to avoid memory leaks.
