Crash in Calculator constructor on strdup

[kbroulik]

I got this downstream KDE bugreport in the KRunner ("Run Command") calculator plugin which uses libqalculate: https://bugs.kde.org/show_bug.cgi?id=365117

I am not able to reproduce the crash using the latest arch packages.

Interesting. Having the same problem. Arch fully updated. Pulled libqalculate source and compiled separately. Same issue, crash when executing "qalc".

Does it still crash if you run LC_ALL=C qalc

@hanna-kn eade7b7#diff-2920795eb5a84823e79c2cfaf6fd7d71R299 commit fixed it for me i think....

[hanscomps]

Fixed, thanks

The cause of this problem is that the locale (specifically LC_NUMERIC) is incorrectly set on the users system. With the commit mentioned above this does not cause a crash with Qalculate! anymore, but the user (or KDE) should still make sure that a valid system locale is set (or at least is left empty).
