Bug ID: 86258
Summary: Program compiled with fPIC crashes while stepping over
thread-local variable GDB
Product: gcc
Version: 4.4.7
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: jlangan at progress dot com
Target Milestone: ---
A detailed description (not mine) and workaround can be found at the address
seen below: (credit goes to those contributors). However, I need an official
patch for this - hence this request
The description starts with:
-----------------------------------------------------
This is a very strange problem which occurs only when the program is compiled
with -fPIC option.
Using gdb I'm able to print thread local variables but stepping over them leads
to crash.
