Upgrade from gcc 2.95 to gcc 3.3.2 causes program to sigsegv.

[Anthony Pun]

Hi Everyone,

We've recently upgraded OS from 11.00 to 11.11 (HP-UX hfiledev B.11.11 U 9000/800 668319303 unlimited-user license), and also our gcc compiler to version 3.3.2...

(/home/apun/test)
hfiledev[20]% gcc -v
Reading specs from /usr/local/lib/gcc-lib/hppa2.0w-hp-hpux11.11/3.3.2/specs
Configured with: /scratch/root/gcc-pkg/3.3.1/hpux-11/gcc-3.3.2/configure --enable-languages=c,c++ --enable-threads=posix --disable-nls --with-gnu-as --without-gnu-ld --with-as=/usr/local/bin/as --prefix=/usr/local
Thread model: posix
gcc version 3.3.2

I'm running into a SIGSEGV on a return statement in one of our programs. GDB output...

#0 0xc019a518 in free () from /usr/lib/libc.2
(gdb) bt

(gdb)

Line 487 of makefile.cpp is a return out of a function.

Anyway, Here's some of the things I've done so far...

- Checked the Kernel parameters.
- Compiled PA-RISC 1.1
- Compiled PA-RISC 2.0 32-bit
- Compiled PA-RISC 2.0 64-bit

Here's a tail of tusc...

Any input would be greatly appreciated. Thanks!

Also, here's where I downloaded gcc 3.3.2 and binutils...

As for gcc is one of the few exceptions to the rule, you need a different gcc on 11i than on 11.00. They are not compatible.

So if you got the gcc-3.3.2 from HP somewhere, be sure to check if it was built on and for 11i, and not for 11.00

If you want to be sure, fetch a gcc-3.3.3 binary including binutils-2.14 and gdb-6.0 from my HP ITRC site.

Thanks for the reply.

I'm sure that the gcc I've installed is for 11.11. I probably should have mentioned, that I've already tried the one off of your website.

A big thanks, for maintaining your website.

Did my version caused segv's too?

Just curious. Cannot do much about it.

Looks like your libstdc is out of date not compliant with your version of GCC. I normally get my GCC and related apps from the HP Porting Archive.

[Anthony Pun]

The one from your site had the same problem. I'm going to rebuild gcc and see if that fixes it.

Thanks.

Rebuild gcc 3.3.2 from source, bootstrap4. Still dumping in libstdc++.sl.5...

Any ideas? Thanks!

Did you set any locale? like in $LANG, or $LC_ALL?

Could you try without, or with $LANG=C?
