Hello, Today I installed musl C x86-64 library next to GLIBC on Linux 86-64 system. It has been installed to /usr/lib/libc.so. I didn't expect any problems with that, in fact all programs were running fine but Firefox couldn't start. The reason is (I think) that /usr/lib/libc.so was chosen by XUL for foreign function call instead of /lib64/libc.so.6. This is what gdb says: Program received signal SIGSEGV, Segmentation fault. 0x00007fffc0f80b82 in strerror_l () from /usr/lib/libc.so (gdb) bt #0 0x00007fffc0f80b82 in strerror_l () from /usr/lib/libc.so #1 0x00007ffff31299a4 in ffi_call_unix64 () from /usr/lib64/firefox-45.0.2/libxul.so #2 0x00007ffff3129050 in ffi_call () from /usr/lib64/firefox-45.0.2/libxul.so Segmentation fault is not strange in such situation, it's normal when a dynamic linker is in different version than libc. After removing musl XUL picked /lib64/libc.so.6 as shown here albeit for a different C function: (gdb) bt #0 0x00007ffff6cb8150 in _xstat () from /lib64/libc.so.6 #1 0x00007ffff31299a4 in ffi_call_unix64 () from /usr/lib64/firefox-45.0.2/libxul.so #2 0x00007ffff3129050 in ffi_call () from /usr/lib64/firefox-45.0.2/libxul.so I cloned gecko-dev repository but I didn't anything related to this issue. Can someone explain what happened here?
