5 gcc 2.95.3 post profile tools crash or hangs - ID: 717720
Last Update: Comment added ( nobody )

binutils (at least 2.12.90.0.9 but probaly other
versions too) are mis-compiled with gcc 2.95.3.

At least slackware 8.1 and *probably* red-hat
7.3 contains this bug. Two symptoms are possible:
infinite loop in post-profile tools (see #618922)
or crash. A typical way to look if you get this
problem on slack 8.1 is to try

$ objdump --debugging /lib/ld-linux.so.2

if objdump hang you are subject to this bug:

crash occur in post profile here:

#0 0x0807b13f in {anonymous}::interesting_symbol
(sym=0x80bb990) at op_bfd.cpp:113
113 if (!(sym->section->flags & SEC_CODE))
(gdb) bt
#0 0x0807b13f in {anonymous}::interesting_symbol
(sym=0x80bb990) at op_bfd.cpp:113


If your are subject to this bug consider to apply
or port the attached file to your binutils. Note
this don't cure the cause of problem (gcc bug)
but work-around the effect of this bug in binutils.
(file is binutils sub-dir)

regards,
Phil

P.S: please let this bug report open, it seems distro
independant and I see no way to fix it in oprofile
