Hi,
|
|
|
|
PR 16581:
|
|
GDB crash on inherit_abstract_dies infinite recursion
|
|
https://sourceware.org/bugzilla/show_bug.cgi?id=16581
|
|
|
|
fixed crash from an infinite recursion. But in rare cases the new code can
|
|
now gdb_assert() due to weird DWARF file.
|
|
|
|
I do not yet fully understand why the DWARF is as it is but just GDB should
|
|
never crash due to invalid DWARF anyway. The "invalid" DWARF I see only in
|
|
Fedora GCC build, not in FSF GCC build, more info at:
