Comment(by cmbarton):

 There are never any error messages because this is not a normal GRASS
 module that goes through the GRASS error system. It simply crashes then
 entire interface. The native error system says that the crash starts at
 gvl_write_char. In the GRASS debug output, the second case crashes after
 the "initialize OK" line.

 If you compare the two debug outputs above, gvl_align_char allocates
 enough memory for a resolution of 2 (1000000 > 349308) but runs twice and
 allocates 2 chunks in the second case.

 gvl_align_data correctly allocates the needed memory in both cases now.

 I'm hoping that this is enough to suggest a fix.

 Michael
