We still have a few local patches that have not yet been upstreamed, but they're all up in the Breakpad issue tracker now:
--
Bug 544936, part 1: Add the ability to generate a minidump of a child process at any time (linux). r=ted
Bug 555309, part 2: Allow a particular subprocess thread to be "blamed" in an OOP minidump. r=bsmedberg
Bug 555309, part 4: Insert an artificial exception stream into non-crash browser-side minidumps. r=bsmedberg
Bug 544936, part 2: Add the ability to generate a minidump of a child process at any time (windows). r=ted

// In order to test StabsReader, we parse a human-readable input file
// describing STABS entries into in-memory .stab and .stabstr
// sections, and then pass those to StabsReader to look at. The
// human-readable file is called a "mock stabs file".
//
// Except for compilation unit boundary lines (described below), each
// line of a mock stabs file should have the following form:
//
// TYPE OTHER DESC VALUE NAME
//
// where all data is Latin-1 bytes and fields are separated by single
// space characters, except for NAME, which may contain spaces and
// continues to the end of the line. The fields have the following
// meanings:
//
// - TYPE: the name of the stabs symbol type; like SO or FUN. These are
// the names from /usr/include/bits/stab.def, without the leading N_.
//
// - OTHER, DESC, VALUE: numeric values for the n_other, n_desc, and
// n_value fields of the stab. These can be decimal or hex,
// using C++ notation (10, 0x10)
//
// - NAME: textual data for the entry. STABS packs all kinds of
// interesting data into entries' NAME fields, so calling it a NAME
// is misleading, but that's how it is. For SO, this may be a
// filename; for FUN, this is the function name, plus type data; and
// so on.
//
// A compilation unit boundary line has the form:
//
// cu-boundary FILENAME
// I don't know if the whole parser/handler pattern is really worth
// the bureaucracy in this case. But just writing it out as
// old-fashioned functions wasn't astonishingly clear either, so it
// seemed worth a try.
