Fair enough.  However, I think this generally is a valid bug
report, so I'm re-opening.

Thanks alot! Actually we missed the difference in optimization_level when comparing 7.3 with 7.4.

This is due to opcode optimization, in this case OPcache produces:

ECHO string("Concatenated string: 0,5 invalidate cache for this class by changing something
here: v1<br />")

This also potentially happens with PHP 7.3; it depends on
opcache.optimization_level.  Using

opcache.optimization_level=0x7FFEBF7F

(i.e. disabling bit 7) makes the code working as expected.

exactly, also with opcache the first call is float is correct with a "," and the second
call is incorrect with a "."

and how does that justify different behavior with or wuthout opcache?

This is due to the fact that displaying floats are locale aware.
