PHP 4.0 Bug #8533: debug assertion failure/access violation (php.exe)

From: marc@guidance.nl Operating system: WinNT4sp6 PHP version: 4.0.4 PHP Bug Type: Reproduceable crash Bug description: debug assertion failure/access violation (php.exe) (this also happens with a brand new CVS (3 jan 2001) setup) using VC6... After modifying the following things - TSRM.dsp -> Unix (CR)LF's to PC-style. - ZendTS files: project settings/custom build for zend_language_parser.y and zend_ini_parser.y-files: removed -S option (and make sure bison can find bison.simple) - php4dllts files: project settings/custom build for parsedate.y-file: remove d-S option and compiling the Debug_TS project, I get some debug assertion failures when I run php.exe (the php.ini is the same as php.ini-dist), followed by an access violation. The debugger reports the following trace: _free_dbg_lk(void * 0x008a0e20, int 1) line 1060 + 26 bytes _free_dbg(void * 0x008a0e20, int 1) line 1001 + 13 bytes free(void * 0x008a0e20) line 956 + 11 bytes virtual_getcwd(char * 0x0012f898, unsigned int 260) line 254 + 12 bytes expand_filepath(const char * 0x0012fa98, char * 0x00000000) line 519 + 17 bytes php_fopen_and_set_opened_path(const char * 0x0012fa98, char * 0x101fb780 ??_C@_01LHO@r?$AA@, char * * 0x102352b8 _php_ini_opened_path) line 235 + 11 bytes php_fopen_with_path(char * 0x101fb774 ??_C@_07OJA@php?4ini?$AA@, char * 0x101fb780 ??_C@_01LHO@r?$AA@, char * 0x00ed5548, char * * 0x102352b8 _php_ini_opened_path) line 410 + 20 bytes php_init_config(char * 0x00000000) line 198 + 24 bytes php_module_startup(_sapi_module_struct * 0x00415410 cgi_sapi_module) line 852 + 12 bytes main(int 2, char * * 0x00ed00b0) line 478 + 11 bytes mainCRTStartup() line 338 + 17 bytes KERNEL32! 77f1b9ea() The Release_TS project does NOT have this problem, but since the debug version does this might indicate a deeper problem... Cheerio, Marc Boeren. -- Edit Bug report at: http://bugs.php.net/?id=8533&edit=1
