GDB output:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000004
-[LFAuthLDAPConfig startSection:sectionName:] (self=0x100710, _cmd=0xc42c,
sectionType=0x101600, name=0x0) at LFAuthLDAPConfig.m:531
531 switch (opcodeEntry->opcode) {
( Line numbers are slightly off because I added some debug code to my tree )
Reason for crash:
Without a new line, the parser is picking up /Authorization as a new config
section. Calls to
parse_opcode will then fail and return a null pointer, which is accessed in the
switch statement
further down.
Possible Resolution:
Check or opcodeEntry == NULL or throw an exception on NULL from method
parse_opcode (TRConfigToken *token, OpcodeTable **tables) in LFAuthLDAPConfig.m
