How to repeat:
Build 5.1.53 without flag --enable-mysql-maintainer-mode=no

Adding two more platforms: 
skade03.norway.sun.com / linux-i686 / i686-pc-linux-gnu
skade04.norway.sun.com / linux-x86_64 / x86_64-unknown-linux-gnu

Sorry more platforms running into the term.c prob:
slid03.norway.sun.com / osx10.6-x86 / i386-apple-darwin10.3.0
slid12.norway.sun.com / osx10.5-x86_64 / i386-apple-darwin9.8.0
slid11.norway.sun.com / osx10.5-x86 / i386-apple-darwin9.8.0
osx-imac-x86.mysql.com / osx10.4-i686 / i386-apple-darwin8.11.1

Bug #59122 was marked as duplicate of this one.

Verified with 5.1.54 on Centos 5.4 on x86_64.

The suggested work-around works for me.
