# This is a test case for bug 27831:

|
#
|
|
# https://sourceware.org/bugzilla/show_bug.cgi?id=27831
|
|
#
|
|
# Prior to fixing this bug, GDB could be caused to assert by doing
|
|
# the following: A simple program with a global was started outside
|
|
# of GDB. Once GDB was started, the symbol file was loaded in an
|
|
# atypical manner via the 'add-symbol-file' command. Then, the
|
|
# program was attached to via the 'attach' command at which time the
|
|
# symbol file was loaded again. Once attached, printing the global
|
|
# variable in the program would trigger the assertion error.
|
|
#
|
|
# This is what the assert looked like:
|
|
#
|
|
# gdb/symtab.c:6599: internal-error: get_msymbol_address:
|
|
# Assertion `(objf->flags & OBJF_MAINLINE) == 0' failed.
