Bug description:Op Code is generated on wrong line
Description:
------------
The op code for the jmp seems to be generated against the wrong line for
the continue. (See script below)
6 9 > EXT_STMT
10 > JMPZ <false>, ->13
7 11 > EXT_STMT
12 > JMP ->8
13 > > JMP ->8
14 > FE_FREE $3
Pasted from Derick
HP unfortunately doesn't reset the line numbers for some of the
generated code:
6 9 > EXT_STMT
10 > JMPZ <false>, ->13
7 11 > EXT_STMT
12 > JMP ->8
13 > > JMP ->8
14 > FE_FREE $3
The JMP in line 12 (and line 13) is generated for line 7, and not 8.
This is something that needs to be fixed in PHP itself
See https://bugs.xdebug.org/view.php?id=1405#c4232
for more info
Test script:
---------------
foreach([1,2] as $value) {
if (false) {
continue;
}
}
