If you request a backtrace in GDB while control flow is within musl – including sycalls made by musl – the result looks like: #0 0x0000000000434b46 in __cp_end () #1 0x0000000000432dbd in __syscall_cp_c () #2 0x0000000000000000 in ?? () i.e. not very helpful. Adding --enable-debug resolves this, and --enable-optimize re-enables optimisations which default to off given the previous flag. 2018-01-27T22:57:10+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-27T22:57:10+00:00 urn:sha1:2875f825fd5a29d94bbfd78b1019ebdedd8d2444 The i686 problem was fixed upstream: https://github.com/llvm-mirror/libunwind/commit/aa805e415f19f50ebc6f5e1e1e4bf9bb7f61816b 2018-01-23T23:39:17+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-23T23:39:17+00:00 urn:sha1:9b13e403761797127fd19a7c13eeb2429eb1c139 2018-01-23T16:05:31+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-23T16:05:31+00:00 urn:sha1:abc1061a656284f6e07008e7fd058a389ab2f33e 2018-01-22T18:14:51+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-12T23:22:06+00:00 urn:sha1:68db72d8cd613f88ea69d37bcd159c4ff659aab1 All musl targets except mips[el] assume static linking by default. This can be confusing https://users.rust-lang.org/t/static-cross-compiled-binaries-arent-really-static/6084 When the musl/mips[el] targets was [added](https://github.com/rust-lang/rust/pull/31298), dynamic linking was chosen because of binary size concerns, and probably also because libunwind [didn't](https://users.rust-lang.org/t/static-cross-compiled-binaries-arent-really-static/6084/8) supported mips. Now that we have `crt-static` target-feature (the user can choose dynamic link for musl targets), and libunwind [6.0](https://github.com/llvm-mirror/libunwind/commits/release_60) add support to mips, we do not need to assume dynamic linking. 2018-01-12T18:26:27+00:00 kennytm kennytm@gmail.com 2018-01-12T18:26:27+00:00 urn:sha1:0d199d56ea3b972499c2c395f5ae35e5bfc0d02d Update musl to 1.1.18 According to http://www.musl-libc.org/download.html: This release corrects regressions in glob() and armv4t build failure introduced in the previous release, and includes an important bug fix for posix_spawnp in the presence of a large PATH environment variable. 2018-01-11T17:57:28+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-04T16:55:04+00:00 urn:sha1:882cd3cf0b662bbdd3c79e0f5ae34bb119c2d4aa 2018-01-08T23:26:47+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-08T23:26:47+00:00 urn:sha1:b5a3f56f7509a70a77b397c262383e27a83c05a5 According to http://www.musl-libc.org/download.html: This release corrects regressions in glob() and armv4t build failure introduced in the previous release, and includes an important bug fix for posix_spawnp in the presence of a large PATH environment variable. 2018-01-03T15:49:13+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-03T15:24:56+00:00 urn:sha1:00b54130874b6a6541626b9b023948440fe11141 2018-01-03T15:49:13+00:00 Marco A L Barbosa malbarbo@gmail.com 2018-01-03T11:39:21+00:00 urn:sha1:10a759130e763206bb961deb4c9da6e0466c71a1 Update libunwind to 39.
