Sure. On an Ubuntu 18.04 / x86-64 system with current trunk, configuring with: ~/toolchain/src/gcc/configure \ --prefix=`pwd` \ --enable-languages=c,c++ \ --disable-multilib \ --disable-bootstrap running `make && make check-libbacktrace` gives the failure described above. Here is the contents of libbacktrace/test-suite.log: ===================================================== package-unused version-unused: ./test-suite.log ===================================================== # TOTAL: 33 # PASS: 32 # SKIP: 0 # XFAIL: 0 # FAIL: 1 # XPASS: 0 # ERROR: 0 .. contents:: :depth: 2 FAIL: mtest_minidebug ===================== no debug info in ELF executable no debug info in ELF executable no debug info in ELF executable no debug info in ELF executable no debug info in ELF executable no debug info in ELF executable no debug info in ELF executable test1: not enough frames; got 0, expected at least 3 test1: [0]: got expected f3 test1: [1]: got expected f2 FAIL mtest_minidebug (exit status: 139) --- Let me know if you need any more info.
