tried once running under valgrind, but that doesn't give more info, no errors
till the point of the stack overflow:

GNU Fortran (GCC) version 4.5.0 20090509 (experimental) [trunk revision 147317]
(x86_64-unknown-linux-gnu)
        compiled by GNU C version 4.5.0 20090509 (experimental) [trunk revision
147317], GMP version 4.2.2, MPFR version 2.3.1.
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
==27399== Stack overflow in thread 1: can't grow stack to 0x7FE801FF8
==27399== Can't extend stack to 0x7FE801700 during signal delivery for thread
1:
==27399==   no stack segment
