Hi Bioconductor,

I am getting a segfault reading a SBML file with rsbml_read. The file is generated by the Metabotools tutorial at https://opencobra.github.io/cobratoolbox/latest/tutorials/tutorialMetabotoolsI.html by saving the Molt model. The sybilSBML function readSBMLmod reads the file with no problem.

I particularly want to read the file with rsbml_read as it returns the data structure that the BiGGR function createLIMFromSBML requires.

> model_1_Molt<- readSBMLmod("./Metabotools/model_Molt.xml")
reading SBML file ... OK
getting the model ... OK
creating S and parsing constraints ... OK
GPR mapping ... OK
cleaning up ... OK
validating object ... OK

> model_2_Molt <- rsbml_read("./Metabotools/model_Molt.xml") 
 *** caught segfault ***
address 0x4c8, cause 'memory not mapped'

Traceback:
 1: rsbml_dom(obj)
 2: rsbml_dom(obj)
 3: rsbml_read("./Metabotools/model_Molt.xml")
