Bug ID: 16565
Summary: SIGSEGV in find_pc_sect_psymtab
Product: gdb
Version: 7.7
Status: NEW
Severity: normal
Priority: P2
Component: mi
Assignee: unassigned at sourceware dot org
Reporter: arnetheduck at gmail dot com
I'm debugging an application through Eclipse on Linux x86_64. When the
application is paused, I get the following SIGSEGV 4 out of 5 times.
I got the backtrace by attaching gdb to to the gdb launched by Eclipse.
In the log window, I see the following being the last ocmmand executed:
613,801 28-list-thread-groups i1
I'm running GNU gdb (Gentoo 7.7 vanilla) 7.7
Backtrace:
