Hi, Rohit
I suspect the "segmentation fault" occurs during the execution of
fluid_synth_sload(). This souldn't occur
even if the soundfont file is malformed.
Please, would you try these 2 simple tests and report each results:
1) First test: use a well know correct sf2 (i.e GUGSv1_47.sf2).
2) Second test: still using JJSF2.SF2, In the source file , add "printf" before
and after fluid_synth_sload() like this:
....
printf("fluidsynth_simpe: start loading the soundfont file\n");
/ *Load the soundfont */
if(fluid_synth_sload(synth, argv[1], 1) == -1)
{
fprintf(stderr, "Failed to load the SoundFont\n");
err = 4;
goto cleanup;
}
printf("fluidsynth_simpe: end loading the soundfont file\n");
.....
Cheers.

Hi, I'm just trying to acquaint myself with FluidSynth by testing out a few
example codes given in the docs.
>
I tried to run the code written here, with a random sf2 file that I found
online. I run into the following warning and segfault. I'm not sure how to
proceed. Please help me out. Thanks.
