I am trying to get the phone alignment with merlin. In merlin/egs/build_your_own_voices/s1， I found 02_prepare_labels.sh, which could get phone_align, but encountered

Error in '...........merlin/tools/festival/bin/festival': free (): invalid next size (fast) : ......

I checked merlin/tools/festival/bin/festival with run"bin/festival" and got the attached screenshoot.

I search the Internet and people said compiling festival with gcc-4.8 will fix this question. Currently, my version is gcc 6.2.0. While I am trying to install gcc-4.8 without administrators right, I got

In file included from ../.././gcc/cp/except.c:1005:0:
cfns.gperf: In function ‘const char* libc_name_p(const char*, unsigned int)’:
cfns.gperf:101:1: error: ‘const char* libc_name_p(const char*, unsigned int)’ redeclared inline with ‘gnu_inline’ attribute
cfns.gperf:26:14: note: ‘const char* libc_name_p(const char*, unsigned int)’ previously declared here

I searched for a long time without finding a solution.
Any idea what I can do? Thanks in advance.
