@petrochenkov those are still necessary since none of the Bitrig changes have been upstreamed. I'm surprised about the OpenBSD shared library part of the patch. @semarie is that still necessary? |

@dhuseby @semarie Please, confirm that all Rust-specific changes in the second commit are still required. (It would be ideal to have an unpatched copy of libbacktrace straight from the gcc repo.) Fixes #28447 r? @alexcrichton

This updates the local declaration of `str_size` to always be 4 bytes instead of platform-dependent as its initialization later on only fills in 4 bytes instead of all the bytes of `size_t`. Originally reported as rust-lang/rust#28447 this was fixed in rust-lang/rust#30908

Update libbacktrace We haven't updated libbacktrace in two years. This is just blindly updating to the latest HEAD; I'd like to see what travis says. It at least builds on my machine, running some tests... This perpetuates the patches from #30908

… of uninitialized bytes in pecoff.c; 3) Fix a use of undefined memory in pecoff.c 1) Note: as we target MINGW here, we still want to look up the symbols via the DWARF method (the native Windows way would be to call the SymFromAddr() function, but that would require .pdb files which MINGW does not produce).

Originally reported as rust-lang/rust#28447 this was fixed in rust-lang/rust#30908 3) In rust-lang/rust#39468 it was discovered that this could cause a crash in libbacktrace due to freeing uninitialized memory, and this specific instance was fixed in rust-lang/rust#39509
