cosmomc seg fault
I'm getting a segmentation fault when running the cosmomc code. Cosmomc, camb and WMAP 5 compile, but when I run the code using the default parameters I get,
Number of MPI processes: 1
Random seeds: 29897, 19192 rand_inst: 1
Computing tensors: F
Doing CMB lensing: T
lmax = 2100
Number of C_ls = 3
Varying 7 parameters ( 0 fast)
reading: params_CMB.covmat
forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image PC Routine Line Source
cosmomc 0000000000C1195F Unknown Unknown Unknown
libpthread.so.0 00000032A7A0DE70 Unknown Unknown Unknown
cosmomc 0000000000C1193B Unknown Unknown Unknown
libpthread.so.0 00000032A7A0DE70 Unknown Unknown Unknown
Any ideas?

Update: It was a problem with LAPACK, sorted now though.

For me the problem occured while cosmomc tried to call a function in LAPACK. I changed my lapack options which sorted it out. There is a similar problem here: http://cosmocoffee.info/viewtopic.php?t=1274
Although slightly different, the advice I gave in that thread is the same as I'd give in this case, just play around with the options until it works.
