GPG segfault when sending signal in SPARC sunOS 5.8
Closed, ResolvedPublic
Actions

Description

Release: 1.4.1

Environment

Connecting remotely using X-Win32 from Windows XP. All commands run in xterm (Terminal) windows remotely through the CDE Window Manager.

Running uname -a gives me: "SunOS kappa 5.8 Generic_117350-15 sun4u sparc SUNW,Sun-Fire-480R"

Running gcc -v gives me:

"Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.8/3.0.4/specs
"Configured with: ../configure 
"Thread model: posix
"gcc version 3.0.4"

Running gmake 3.79.1 built for sparc-sun-solaris2.8

Description

I compiled, built, and verified GPG with no errors. However, when running GPG it segfaults if I send a SIGINT (using Control-C) as soon as GPG starts (when run with no options).

I compiled GPG using configure --prefix=/home/8/kornel --enable-static-rnd=auto --disable-card-support --disable-nls --disable-regex --without-photo-viewer. I built it using gmake -j 2. The build complted with warnings but all tests (gmake check) completed with no errors.

I rebuilt it, giving the same options to configure along with "CFLAGS=-g" to turn on debugging (if it wasn't on already). I built with a few warnings bug no errors and checked OK. I ran GPG (with no command-line options) through the GDB debugger, sending it the SIGINT signal as soon as it prompted for input. Here's what I got when I sent the signal:

"Program received signal SIGSEGV, Segmentation fault.
"0xff3284ac in rl_redisplay () at ../display.c:514
"514 ../display.c: No such file or directory."

How To Repeat

Download & verify GPG 1.4.1
Unpack and run ./configure
Run gmake -j 2 to build
Run gmake check to verify
Run gmake install to install
Open new terminal window and run gpg. When prompted for input enter Control-C to send SIGINT (or you could also send SIGTERM).
At this point, GPG should have exited cleanly. Instead, GPG segfaulted.

Would you mind to rebuild it by adding the option
--with-readline=/nowhere
to the configure run. This should create a build without readline support.

What is your version of the readline library? Is that the standard GNU one or an reimplementation?

I reconfigured with `CFLAGS=-g --prefix=/home/8/kornel --enable-

static-rnd=auto --disab
le-card-support --disable-nls --disable-regex --without-photo-viewer
--with-read
line=/nowhere` as requested. gmake and gmake check both
completed, though some warnings were generated during the build.
Unfortunately, I got the same error. Here's the transcript of my
running gpg through gdb:

I am not sure which version of readline I have.  Running `man

readline` lists "GNU Readline 4.2" in the footer. The readline
header files have the GNU GPL included at the top of each header.

Can you try the same test but use --without-readline instead of the
/nowhere path?

Configured with options 'CFLAGS=-g --prefix=/home/8/kornel --

enable-static-rnd=auto --disable-card-support --disable-nls --disable-
regex --without-photo-viewer --without-readline'. Make and make
check ran as before (some warnings on make but no tests failed).

It worked this time.  On sending SIGINT GPG responded "gpg:

signal 2 caught ... exiting" and exited cleanly.

This was a readline problem. Workaround given.
