[Bug rtl-optimization/42489] New: Function call never happened after compile with -foptimize-sibling-calls

[t66667 at gmail dot com]

In function __xmlRaiseError of error.c ( libxml2.a ) if this particular c file
is compiled with optimization -O2 ( -foptimize-sibling-calls ) call to this
function from xmlFatalErrMsgStrIntStr() parser.c ( libxml2.a ) will never take
place, and, seems to cause dead-lock situation.
Tested recompile this c file with, -fno-optimize-sibling-calls, confirm to
workaround the bug.
