Hi,

I remember having had problems in compiling SW-packages when options for optimizing AND for debugging were specified.
Perhaps you try a compilation without '-g' or '+O2'.

H.Merijn Brand (procura — Thu, 04 May 2006 10:53:33 GMT

Already did so.

For most of these files dropping to +O1 is enough, for others +O0 is required

Dropping -g is also OK.

Anyway, IMHO the compiler/optimizer should not crash, but either give me a sensible warning, or drop to a (for the optimizer) accepable level/combination.

Hi Merijn,

Perhaps, you could try installing latest Libc patch PHCO_33609.

HI Merijn,

Sorry for the second post. I just now remember i had this same problem two years ago while trying to build Xerces or Xalan. If i remember correctly, it turned out to be a compiler bug.

I remember i got replies from both Dennis Handley and Steve from HP about this.

P.S Assign zero points.

H.Merijn Brand (procura — Thu, 04 May 2006 12:40:29 GMT

I swapped the points :)

Well you got a reply from them that it is a bug. WHAT WAS THEIR ANSWER?
Are they going to fix it?

Can I `confirm' your bug number?

Enjoy, Have FUN! H.Merijn [ who hates to see an area where gcc does better than HP C-ANSI-C ]

I guess there are 2 issues invloved, one for stack trace and second for Signal 11.

I would take a look at these patches as similar issues have been taken care of

PHSS_33902
PHSS_34412

Re: HP C ANSI C optimizer broken on HP-UX 11.11

Sameer_Nirmal — Thu, 04 May 2006 15:47:39 GMT

Typo..
Correction...
Instead of PHSS_33902, wanted to mention PHSS_33901.

hi

can you file a defect for this ? or post a .i file which can reproduce the problem, so that i can file a defect for you.

thanks
ranga

H.Merijn Brand (procura — Fri, 05 May 2006 03:24:09 GMT

Sameer. thanks for searching, but if you would have had a closer look at the what output for cc, you could have seen that the PHSS_34412 was already in:

HP92453-01 B.11.X.34412-34415.GP HP C Compiler

I do not have confidence in the second patch. This is a production system, and as - from the description - I see no resolution in the defects these patches fix, and they only have one star, I'll just wait for the next goldpack.

ranganath, you could generate it yourself most likely.

# cd /tmp
# mkdir perl-devel
# cd perl-devel
# rsync -avz rsync://public.activestate.com/perl-current/ .
# sh ./Configure --Dusedevel -Duse64bitall -DEBUGGING=both -des
# make

... boom ...

Enjoy, Have FUN! H.Merijn
