- Subject: MIPS: firefox binary with broken MIPS_RLD_MAP tag
Building firefox-8.0 natively on MIPS results in a broken binary which
segfaults during startup in libc, due to a zero "MIPS_RLD_MAP" tag in
the dynamic section:
Dynamic section at offset 0x1dc contains 31 entries:
Tag Type Name/Value
0x00000001 (NEEDED) Shared library: [libpthread.so.0]
0x00000001 (NEEDED) Shared library: [libdl.so.2]

0x00000001 (NEEDED) Shared library: [libgcc_s.so.1]

0x70000011 (MIPS_SYMTABNO) 75
0x70000012 (MIPS_UNREFEXTNO) 42
[...]
After removing the broken 0x70000016 tag firefox loads and runs.
(gcc-4.6.2, binutils-2.22, glibc-2.14.1).
Please have look at this.
Thanks!
