I'm seeing this for example with sassc crashing while trying to build x11-themes/greybird-theme. My first suspect was the llvm upgrade in head, but forcing sassc and libsass to build with older clang via USES=llvm:max=18 is not helping. I did recompile the offending programs with debug and tried a backtrace and got this: ``` (lldb) bt * thread #1, name = 'sassc', stop reason = signal SIGSEGV: invalid permissions for mapped object (fault address: 0x82374a000) * frame #0: 0x000000082374a000 libsass.so.1 frame #1: 0x0000000823865a86 libsass.so.1`_GLOBAL__sub_I_ast.cpp [inlined] double std::__1::__math::acos[abi:se190102](__x=-1) at inverse_trigonometric_functions.h:40:10 frame #2: 0x0000000823865a81 libsass.so.1`_GLOBAL__sub_I_ast.cpp [inlined] __cxx_global_var_init at units.hpp:11:21 frame #3: 0x0000000823865a81 libsass.so.1`_GLOBAL__sub_I_ast.cpp at ast.cpp:0 frame #4: 0x00001eac6e3f078d ld-elf.so.1 frame #5: 0x00001eac6e3ef349 ld-elf.so.1 frame #6: 0x00001eac6e3ec099 ld-elf.so.1`___lldb_unnamed_symbol27 + 25 ``` which points me to this upstream line of code: https://github.com/sass/libsass/blob/7037f03fabeb2b18b5efa84403f5a6d7a990f460/src/units.hpp#L11 I could change the way it derives PI, but I'm not sure this is the correct fix. Thanks in advance for any insight! -- Guido Falsi
