Running with --debugmsg +heap you get something like:
0806feb0:Call msvcrt.strcat(403a4005 "Cygwin/bin/",403a3fb0 "/pinco/panco") ret=004014f2
0806feb0:Ret  msvcrt.strcat() retval=403a4005 ret=004014f2
0806feb0:Call msvcrt.free(403a3fac) ret=00401501
0806feb0:Call kernel32.HeapFree(403a0000,00000000,403a3fac) ret=42563e35
err:heap:HEAP_ValidateFreeArena Heap 403a0000: prev arena 403a401c invalid for 403a0344
Heap: 403a0000

This looks like heap corruption. In 
URLParser.cc:127:        strcat ((char *) path, schema);
you scribble to path, but you have no storage allocated for path.

So recheck you code.
