Alexandre,
I am uncertain if the stock dwarfdump will provide the necessary
information to find any residual zero locations. I have uploaded
an archive of the remaining shared libs that cause dsymutil to
assert under radar://7415099 and have asked the darwin linker
maintainers to look at those. I'll let you know as soon as I hear
back if this is still the same issue with zero locations or something
different. Remember that they have been working from the limited
testcase in PR41473 and haven't tested full shared libs from FSF
gcc yet with their patched dsymutil. I specific it may still be
the zero locations problem though because dsymutil is stil asserting
on the same line...
Assertion failed: (orig_str), function FixReferences, file
/SourceCache/dwarf_utilities/dwarf_utilities-70/source/DWARFdSYM.cpp, line 3641.
Abort
Jack
