rrdtool v 1.8.0 - Segmentation fault on start (Alpine Linux)

[goricz]

Describe the bug

# rrdtool 
RRDtool 1.8.0  Copyright by Tobias Oetiker <tobi@oetiker.ch>
Segmentation fault (core dumped)

Older version 1.7.2 is running well

see https://gitlab.alpinelinux.org/alpine/aports/-/issues/15416

To Reproduce
Steps to reproduce the behavior:

1. install rrdtool v. 1.8.0 in Alpine Linux
2. run rrdtool

Desktop (please complete the following information):

• OS: Alpine Linux
• Version 3.18+

Additional context
It's failing because of this commit:
6040d8f

If BUILD_DATE is defined, there is the last parameter missing in fprintf()

#ifdef BUILD_DATE
    fprintf(stdout, _(help_main), PACKAGE_VERSION, BUILD_DATE);
#else
    fprintf(stdout, _(help_main), PACKAGE_VERSION, __DATE__, __TIME__);
#endif

I've tried to compile with empty string in place of last parameter:
fprintf(stdout, _(help_main), PACKAGE_VERSION, BUILD_DATE, "");

and it worked well

Thanks, I didn't notice that patch.
I'll include it in rrdtool APKBUILD.
