The following:
import std.regex;
void main()
{
string s = "$,";
replace(s, regex("$",","), ""); // Is this possible? If so, what is
the propper way to do it?
assert(s == "", s);
}
Compiled with dmd.2.039, 042, 048, and 049 but yields a runtime error:

Error 42: Symbol Undefined __d_throwc

I grepped my hard drive for _d_throwc and found the following:

Redundant entries were removed for brevity.
Function _d_throwc is defined on line 152 of
dmd2\src\druntime\src\rt\deh2.d and line 232 of
dmd2\src\druntime\src\rt\deh.d. I do not know how to correct the problem
however it does seem odd that Linux's libphobos2.a uses the same name as
was originally defined "_d_throwc" while OSX's libphobos2.a,
druntime.lib and phobos.lib are different. Note that this function did
not exist prior to dmd.2.050. Don't know if it matters but I'm using
Win7. Any assistance is appreciated.

That bit of info actually fixed linker error portion of my problem. Seems my copy of dmd 2.050 got corrupted. Trying to run the program still results in the runtime error above. Any ideas? Thanks, Andrew
