Confirmed.

Missing separate debuginfos, use: debuginfo-install libgcc-4.4.7-18.el6.x86_64
libstdc++-4.4.7-18.el6.x86_64 pcre-7.8-7.el6.x86_64
gdb$ record full
gdb$ set record full insn-number-max 2000000
gdb$ c
Continuing.
Process record does not support instruction 0xf6f at address 0x33af241b20.
Process record: failed to record execution log.

Program stopped.
__mpn_lshift () at ../sysdeps/x86_64/lshift.S:26

gdb$ x /i $pc
