Comment(by robe):

 realityexists - I think this is the issue with error handling I was using.

 Try with 9.3 windows 7 64-bit: works on my windows 7 9.3 64-bit 2.1.2dev
 fine.

 The issue I think is with the way errors were being handled.  For 9.2
 64-bit windows I compiled with gcc 4.5 which only had long jump handling.
 Unfortunately I ran into some situations like this where the errors were
 not handled properly.  I think some were the ones you reported in fact.

 For 9.3 and moving forward for 64-bit windows, I've been using gcc 4.8
 with SEH (structure error handling), which doesn't seem to have this
 issue.  long jump works fine for 32-bit so 32-bit windows never exhibited
 this issue (in fact because of patent issue seh is not available for
 windows 32-bit anyway) but I do compile 9.3 32-bit with gcc 4.8 also.

 Short answer -- just upgrade to 9.3 for windows and the issue should go
 away.  I've been debating recompiling 9.2 postgis with 4.8 but there
 weren't enough people complaining for me to warrant the risk of causing
 more damage (since if a person is running both PostGIS 2.0 and 2.1 under
 9.2 -- an upgrade of one would break the other since the gcc 4.5 and 4.8
 chains are not compatible). I also wasn't sure if I would run into issues
 with the 4.8.  So far 4.8 has been really good, so I may just bite the
 bullet and redo 9.2 or at least offer gcc48 compiled 9.2 PostGIS for those
 who really want it.
