During testing with R-devel on the alpha I just noticed (after misspelling
"bin/R" as "bin/R.bin") that R.bin segfaults. It accesses the empty R_HOME
variable and should better give an error instead of a crash:
a gdb output snippet:
...
Program received signal SIGSEGV, Segmentation fault.
0x3ff800d6a10 in strcpy ()
(gdb) backtrace
#0 0x3ff800d6a10 in strcpy ()
#1 0x1200efda0 in R_load_X11_shlib () at dynload.c:454
#2 0x1200ecc88 in main (ac=1, av=0x11fffef28) at system.c:160
(gdb) up
#1 0x1200efda0 in R_load_X11_shlib () at dynload.c:454
454 strcpy(X11_DLL, getenv("R_HOME"));
some test for getenv returning NULL followed by exit(1) would be
better.
