Bug#950008: Sv: Bug#950008: gfan: assertion fails on riscv64

[Anders Nedergaard Jensen]

Hi,

Thanks for the bug report.
Line 30 of application.cpp looks suspicious:
  while(p[l]!=0 && p[l]!='/');
Does it help to change it to
  while(l!=0 && p[l]!='/');
?
If not, I think I need to know what the char* argv[0] points to when main is  called.

Best regards,
Anders
