Subject: debug/2714: Stabs truncated on AIX
Date: Wed, 02 May 2001 09:36:00 -0000 [thread overview]
Message-ID: <20010502163540.11449.qmail@sourceware.cygnus.com> (raw)
>Number: 2714
>Category: debug
>Synopsis: Stabs truncated on AIX
>Confidential: no
>Severity: serious
>Priority: medium
>Responsible: unassigned
>State: open
>Class: sw-bug
>Submitter-Id: net
>Arrival-Date: Wed May 02 09:36:01 PDT 2001

>Originator: Bor Chan
>Release: 2.95.2
>Organization:
>Environment:
AIX
>Description:
gcc believes that it can emit arbitrarily long stab strings
on AIX (xcoffout.h contains #define DBX_CONTIN_LENGTH 0).
Howeverm the assembler truncates stabs trings after 32767
characters.
In C++ code using the STL it is possible to exceed this limit.
>How-To-Repeat:
Compile the code -g and then objdump --syms the .o file.
Observe that the stabs for _Rb_tree<basic_string<char,string_char_traits<char>,
etc... is truncated after 32767 characters.
>Fix:
Turn on stab continuations in xcoff.
You might also need to worry about the fact that IBM use
? as the continuation marker, rather than \ as the last
character of a continued stab.
