["Falk Hayn" <Falk.Hayn@xxxxxx>]

Dear Ladies and Sirs, Dear Guy Harris,Dear Olivier Biot,
Dear core-developpers,

searching the error message pattern fv->ftype->set_value
in the dev mailing list archive leads to at least 9 hits.
( 1st occurance of problem in Dec. 2003 )
-> Problem is outstanding for at least 6 month.

******
Recommended workarounds: reduce optimization level
******

I reduced the optimization level from -O2 to -O, this modified 
ethereal build completed and the resulting binaries do not crash.
( I was lazy: vi configure, search O2, replace O)


All dev mailing list threads I read, seems to have the same pattern:
- does not depend on GTK version, I�m still using GTL 1.2.10
- 64 bit enabled operating system (64 bit linux, 64 bit HP-UX 11.11)
- gcc 3.3.x    (I do have gcc 3.3.3)


important question: Who of the core developpers has a 64 bit machine (SPARC,
ITANIUM, AMD64, with gcc 3.3.x  *and* does not (!) see the problem ?


Pls. let me know what You think.


With regards
F.

Subject: ethereal-0.10.4: crash on HP-UX 11.11 - with backtrace in debugger
session

Dear Ladies and Sirs,

pls. find a backtrace from active debugger session:

Who has an idea what the root cause of the 1st "dangerous looking" message
in the backtrace may be ?
(Well, runnig a pgm in debugger may create bogus msgs, but this looks really
true... ;-)  :

#7  0x7a557a28 in proto_tree_set_ether (fi=0x6, value=0x46b <Error reading
address 0x46b: Bad address>) at proto.c:1442

Who can give advice�s to drill down the problem further ?
