Lexer crash on `...>=(...)...`

SyntaxError: Unexpected "=" (parser)

Note: crash is flaky. Sometimes compilation passes and generates:

# Generated with SMOP  0.41-beta
from libsmop import *
# fcn.m

@function
def fcn(A=None,*args,**kwargs):
    varargin = fcn.varargin
    nargin = fcn.nargin

    B=A >= (A)
# fcn.m:2
    return B

if __name__ == '__main__':
    pass

Workaround: try compilation multiple times. Looks like it works 1 in 10 times 100% of the times :)

Having similar problem. Will try your work-around:

File "dloslab.m", line 179

[r b]= deal(var(1,:)'>=delta*varmax & YL(:,5)~=2, var(1,:)'<=-delta*varmax & YL(:,5)~=2);
