Sorry to not clear enough previously, for Turkic locales (tr_TR, az_AZ etc.) upper(i) != I. More detailed analysis can be found at http://www.i18nguy.com/unicode/turkish-i18n.html, "Why Applications Fail With The Turkish Language" section. This is the main reason of this problem.
According to its man page signals defined with uppercase letters but also different trap implementations may permit lowercase signal names as an extension.
As an example bash (v. 3.1.17) permits lowercase signal names but it converts this lowercase signal names into uppercase ones while interpreting the script. But for our "Turkish has 4 letter "I"s" problem this convert to uppercase one process fails but for bash invalid signal names not be considered a syntax error and do not cause the shell to abort.
