Exception and pthread on HPUX

Exception and pthread on HPUX

[Michael GZ]

Hi

Anybody here has experience with working GCC on HPUX.
Is there anything special to handle exception in a
multi-threaded application running on HPUX 11.00.

My application is a kind of complex multi-threaded
server with a lot of network communications. Currently
my problem is that whenever there is an exception
raised, the application got core dump. I tried to
ignore several signals such SIGSEG, etc, still the
same thing.

We used to compile our application several months ago
with old gcc, it was working perfercetly. Unforunatly,
the old gcc got overwritten by new installation.


Environment:
HPUX 11:00
GCC 3.3.2 (I downloaded from HPUX porting center)

Thanks in advance

Michael

I only have patch numbers for HP-UX 11.22 and 11.23.  I don't know if
equivalent patches exist for 11.00 or 11.11.

<http://itrc.hp.com/service/patch/patchDetail.do?patchid=PHSS_30215>  (11.22)
<http://itrc.hp.com/service/patch/patchDetail.do?patchid=PHSS_30017>  (11.23)

I can do that later this afternoon; feel free to beat me to it.

We should add a pointer to the HP-UX patch to 

http://gcc.gnu.org/install/specific.html

(or to whatever texinfo file is used to generate that page).

There is an HP-UX libunwind patch that you should install.  That 
libunwind patch fixes a number of SEGVs during exception unwinding.

Zack, do you have the README with that linker patch number?
