release only bug?
Author
okay im upgrading my project from vc2005 to vc2008 and my app works fine in debug mode, but now in release mode i get a crash.
i've tracked it down to
some code like this:
the crash is in 'regex_search'
now the weird thing is, i copied this code in to the main project, and it worked, but still continues to crash in this code that is in a seperate project (which compiles to a lib).
any thoughts?
the call stack ends up in:
_invalid_parameter_noinfo
called from from boost::match_results
by the way my boost libs were compiled in vc2005
Boost is "untested" on vc2008. You should be getting compiler warning about it. I've had no problems, but I don't use boost::regex.
This doesn't look like a "crash," but rather an unchecked exception. Use the stack trace to find which function threw the exception and look at the documentation (or if you're brave enough, the source code) for that function and find out why it threw it.

Sometimes bugs that appear in release conf only are caused by non unitialized memory (debug initializes allocated memory IIRC).

Change to this:
char line[] = "[game]"; // fixed
The difference is assigning a string literal to a char* will assign the address of the literal in a string table, while assigning it to a char[] will copy the string from the table to an array on the stack. Apparently you're able to write to strings in the string table in debug mode, but not release mode? I know you're not able to write to the string table at all on Linux/GCC, not sure about MSVC.

Why would a regex_search write to the searched string, though? o_O
You're right, I spoke too soon. The problem lies elsewhere. regex_search() takes a const char * as the first parameter.
