Bug ID: 16292
Summary: GDB Oversteps a range in some cases.
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: breakpoints
Assignee: palves at sourceware dot org
Reporter: saugustine at google dot com
Log below shows gdb 7.6, but I have reprod with top of trunk.
Situation is a heavily multi-threaded application, setting a breakpoint and
stepping over a line or two with "n". We have also seen it with "fin". More
details to follow.
I have unsuccessfully tried to find a small test case, but at least one place
this happens is while debugging the chrome web browser, which is very much not
small.
../../gdb-7.6.x/gdb/infrun.c:1965: internal-error: resume: Assertion
`pc_in_thread_step_range (pc, tp)' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) y
Some work has been done here that isn't quite right, but is at least in the
neighborhood.
