[Buildroot] minicom aborts

[David PICARD]

Hello,
 
When I try to start minicom, some test fails, and minicom quits straight away :

# minicom
minicom: minicom.c: 1041: test_mbswidth: Assertion `mbswidth(e[i].s) == e[i]._mbswidth || mbswidth(e[i].s) == e[i]._mbswidth_kaputt' failed.
Aborted
 
The minicom.c file can be found here :
https://salsa.debian.org/minicom-team/minicom/blob/master/src/minicom.c
 
My only locale is "C".
 
I'm not sure if it's a bug in minicom or if something is missing on my system.
