  The info files output confirms there's nothing unusual loaded into the
process memory.  That makes me think it's not BLODA.  The presence of
cyggmp-3.dll in the stack trace is interesting; that stack trace looks like
it's probably correct, and we are running start-up constructors.

  Now, this is interesting.  All your DLLs are in very different places to
mine, in a working instance of expr.exe:

        0x63f41000 - 0x63f84db8 is .text in /usr/bin/cyggmp-3.dll
        0x63f85000 - 0x63f88e54 is .data in /usr/bin/cyggmp-3.dll
        0x63f89000 - 0x63f89004 is .rdata in /usr/bin/cyggmp-3.dll
        0x63f8a000 - 0x63f8a170 is .bss in /usr/bin/cyggmp-3.dll
        0x63f8b000 - 0x63f8f8c6 is .edata in /usr/bin/cyggmp-3.dll
        0x63f90000 - 0x63f90410 is .idata in /usr/bin/cyggmp-3.dll
        0x63f91000 - 0x63f92680 is .reloc in /usr/bin/cyggmp-3.dll
        0x6f5c1000 - 0x6f5c6558 is .text in /usr/bin/cygintl-8.dll
        0x6f5c7000 - 0x6f5c703c is .data in /usr/bin/cygintl-8.dll
        0x6f5c8000 - 0x6f5c8854 is .rdata in /usr/bin/cygintl-8.dll
        0x6f5c9000 - 0x6f5c95d8 is .bss in /usr/bin/cygintl-8.dll
        0x6f5ca000 - 0x6f5ca5ae is .edata in /usr/bin/cygintl-8.dll
        0x6f5cb000 - 0x6f5cb7e0 is .idata in /usr/bin/cygintl-8.dll
        0x6f5cc000 - 0x6f5cc460 is .reloc in /usr/bin/cygintl-8.dll
        0x674c1000 - 0x674d6fe8 is .text in /usr/bin/cygiconv-2.dll
        0x674d7000 - 0x674d7008 is .data in /usr/bin/cygiconv-2.dll
        0x674d8000 - 0x675b481c is .rdata in /usr/bin/cygiconv-2.dll
        0x675b5000 - 0x675b54b8 is .bss in /usr/bin/cygiconv-2.dll
        0x675b6000 - 0x675b6172 is .edata in /usr/bin/cygiconv-2.dll
        0x675b7000 - 0x675b734c is .idata in /usr/bin/cygiconv-2.dll
        0x675b8000 - 0x675b8d00 is .reloc in /usr/bin/cygiconv-2.dll

  So I think you must have rebased, yes?  Interesting.

  Those all look sensible.  Right, I think I have a guess what's going on.
Please try re-installing libgmp3 using setup.exe and see if it solves the
problem for you.  I think this might be the same as
