Bug#422830: binutils: ld segfaults when linking (C++?) PIC object with non-PIC object

[Sven Neumann]

Same problem here, the linker crashes with a segmentation fault.
Downgrading to binutils 2.17cvs20070426-4 fixes it.

The severity of this bug should better be increased so that it doesn't
hit lenny.

Bug#422830: binutils: ld segfaults when linking (C++?) PIC object with non-PIC object

[Tommi Vainikainen]

Package: binutils
Version: 2.17cvs20070426-5
Severity: normal

I was trying to link PIC object with non-PIC object to create dynamic
library (.so). However after upgrading to -5 ld segfaults with
following backtrace.

Downgrading binutils to -4 is a quick fix for this. Version -4 does
not give segmentation fault in this situation.

Here are commands:

g++ -c  -o a.o a.cpp
g++ -c -fPIC  -o b.o b.cpp
g++ -shared -L. -o ab.so a.o b.o
collect2: ld terminated with signal 11 [Segmentation fault], core dumped
make: *** [ab.so] Error 1

Here is a backtrace from core:

(gdb) bt
#0  0xb7e785cc in _bfd_elf_discard_section_eh_frame ()
