c++ - Forward declaration of array of QStrings leads to segmentation fault -



c++ - Forward declaration of array of QStrings leads to segmentation fault -

in code have 2 forwards declarations, bool array , qstring array in namesace nlog.

bool works. qstring produces segmentation fault.

header:

class log : public qobject { explicit log(); public: enum facility { third_party_fac, test_fac, __facility_last_element }; enum severity { debug_sev, warning_sev, critical_sev, fatal_sev, __severity_last_element }; }; namespace nlog { extern bool logging_enabled[log::__facility_last_element][log::__severity_last_element]; extern qstring severity_name[log::__severity_last_element]; }; class logstaticinitiallizer { public: logstaticinitiallizer(); }; static logstaticinitiallizer initiallizer=logstaticinitiallizer();

source:

qstring nlog::severity_name[log::__severity_last_element]; bool nlog::logging_enabled[log::__facility_last_element][log::__severity_last_element]; using nlog::logging_enabled; using nlog::severity_name; logstaticinitiallizer::logstaticinitiallizer() { qdebug()<<"0"; qdebug()<<logging_enabled[0][0]; qdebug()<<severity_name[0]; qdebug()<<"1"; }

it produces

0

false

and crashes @ qstring trace

as piotr s. said, problem logstaticinitiallizer constructor called before initialization in source file.

also, there unrelated main problem reserved identifiers starting __. see what rules using underscore in c++ identifier?

Php operator `break` doesn't stop while - have weird issue, break doesn't break while loop , maintain rotating. logically should break cycle , set output while ($c++ != 5) { // here curl request, doesn't relevant have removed preg_match("!<.*?>(\s*)[^<>]*?{$to}<!", $resp, $result) ; // echo 'cnt = ' .count($result).'<br>'; if(!count($result)) { $amount = 0; echo 'sleep called'; sleep(4); exit; continue; } else { $amount = trim(@$result[1]); $amount = round($amount + $amount * $exchange_ratio, $precision); echo 'break happen<br>'; break; } } so output cnt = 2 break happen cnt = 0 sleep called so skipped break , maintain rotating. how so? edit works fine on localhost issue php version? ...
