>Description:
After r251672 /usr/lib/libc.so becomes a plain ASCII text file which contains a linker script.
Unfortunately, now dlopen("libc.so") fails because it's not an ELF file, resulting applications which depend on dlopen("libc.so") get broken.
Applications which are broken by r251672 currently I know includes, but potentially not limited to:
- Firefox (it boots, but exhibits broken behaviour)
- Mono applications which P/Invoke libc functions (ends up with System.DllNotFoundException: libc.so)
>How-To-Repeat:
Firefox case:
Launch Firefox with libmap.conf empty.
Firefox boots, but it won't load the previous session, URL bar won't navigate us anywhere, etc.
Mono applications which use libgdiplus, or anything which P/Invoke's libc's functions:
Launch such applications with libmap.conf empty.
They ends up with: System.DllNotFoundException: libc.so
>Fix:
Note this is only a workaround!
Put the following line into libmap.conf:
libc.so libc.so.7
