Description John Reiser 2001-03-23 05:29:03 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.2.5-15 i586)


gdb gets lost reading dwarf2 info for a shared library,
quits early, and does not see most of the symbol information,
leaving the user nearly helpless.

Reproducible: Always
Steps to Reproduce:
1. compile and link shared library
2. invoke gdb
3.
I will Attach the linked .so (42KB) and C++ source file (26KB)
and shell script to this Bug, as soon as the Bug number is reported
to me.

Actual Results:  $ ./Bar.sh
Bar.cc:817: warning: `class Class1::Class000000000033' only defines 
private constructors and has no friends

Comment 4 Trond Eivind Glomsrxd 2001-03-23 21:45:59 UTC 
Any chance of trying a newer gdb, eg. the newest daily snapshot in
ftp://sources.redhat.com/pub/gdb/snapshots ?
Comment 5 John Reiser 2001-03-23 22:51:10 UTC 
It still fails on today's snapshot:

Comment 6 Trond Eivind Glomsrxd 2001-04-06 19:49:53 UTC 
I've built gdb-5.0rh-6. You can find them in http://people.redhat.com/teg/gdb/ ?

Can you give these a try, to see if they fix this problem on the IA64?
Comment 7 Paul Pluzhnikov 2001-04-08 22:11:52 UTC 
John no longer has access to the IA-64 system.

My results using http://people.redhat.com/teg/gdb/gdb-5.0rh-6:
no change in behaviour

Comment 8 Jakub Jelinek 2001-04-28 18:08:29 UTC 
Should be fixed in gcc-2.96-82.
